When using the XML Reader interface with DTD validation and XInclude expansion enabled, processing crafted XML documents can lead to an xmlValidatePopElement use-after-free. Affected range >=2.12.7+dfsg+really2.9.14-0.1 Fixed version Not Fixed EPSS Score 0.07% EPSS Percentile 32nd percentile Description libxml2 through 2.11.5 has a use-after-free that can only occur after a certain memory allocation fails. This occurs in xmlUnlinkNode in tree.c. NOTE: the vendor's position is "I don't think these issues are critical enough to warrant a CVE ID ... because an attacker typically can't control when memory allocations fail." Affected range >=2.12.7+dfsg+really2.9.14-0.1 Fixed version Not Fixed EPSS Score 0.06% EPSS Percentile 28th percentile Description Xmlsoft Libxml2 v2.11.0 was discovered to contain an out-of-bounds read via the xmlSAX2StartElement() function at /libxml2/SAX2.c. This vulnerability allows attackers to cause a Denial of Service (DoS) via supplying a crafted XML file. NOTE: the vendor's position is that the product does not support the legacy SAX1 interface with custom callbacks; there is a crash even without crafted input. Affected range >=2.12.7+dfsg+really2.9.14-0.1 Fixed version Not Fixed EPSS Score 0.04% EPSS Percentile 11th percentile Description An issue was discovered in xmllint (from libxml2) before 2.11.8 and 2.12.x before 2.12.7. Formatting error messages with xmllint --htmlout can result in a buffer over-read in xmlHTMLPrintFileContext in xmllint.c.

Affected range >=1.21.3-3 Fixed version Not Fixed EPSS Score 0.04% EPSS Percentile 10th percentile Description Kerberos 5 (aka krb5) 1.21.2 contains a memory leak vulnerability in /krb5/src/kdc/ndr.c. Affected range >=1.21.3-3 Fixed version Not Fixed EPSS Score 0.10% EPSS Percentile 42nd percentile Description An issue was discovered in MIT Kerberos 5 (aka krb5) through 1.16. There is a variable "dbentry->n_key_data" in kadmin/dbutil/dump.c that can store 16-bit data but unknowingly the developer has assigned a "u4" variable to it, which is for 32-bit data. An attacker can use this vulnerability to affect other artifacts of the database as we know that a Kerberos database dump file contains trusted data. Affected range >=1.21.3-3 Fixed version Not Fixed EPSS Score 0.04% EPSS Percentile 10th percentile Description Kerberos 5 (aka krb5) 1.21.2 contains a memory leak in /krb5/src/lib/rpc/pmap_rmt.c.

libgcrypt20 1.11.0-6 (deb) pkg:deb/debian/[email protected]?os_distro=trixie&os_name=debian&os_version=unstable Affected range >=1.11.0-6 Fixed version Not Fixed EPSS Score 0.04% EPSS Percentile 10th percentile Description A timing-based side-channel flaw was found in libgcrypt's RSA implementation. This issue may allow a remote attacker to initiate a Bleichenbacher-style attack, which can lead to the decryption of RSA ciphertexts. Affected range >=1.11.0-6 Fixed version Not Fixed EPSS Score 0.19% EPSS Percentile 57th percentile Description cipher/elgamal.c in Libgcrypt through 1.8.2, when used to encrypt messages directly, improperly encodes plaintexts, which allows attackers to obtain sensitive information by reading ciphertext data (i.e., it does not have semantic security in face of a ciphertext-only attack). The Decisional Diffie-Hellman (DDH) assumption does not hold for Libgcrypt's ElGamal implementation.

NOTE: the software maintainer disputes that this is a vulnerability because the behavior occurs only with a crafted pattern Affected range >=2.40-3 Fixed version Not Fixed EPSS Score 0.35% EPSS Percentile 72nd percentile Description GNU Libc current is affected by: Mitigation bypass. The impact is: Attacker may guess the heap addresses of pthread_created thread. The component is: glibc. NOTE: the vendor's position is "ASLR bypass itself is not a vulnerability. Affected range >=2.40-3 Fixed version Not Fixed EPSS Score 3.02% EPSS Percentile 91st percentile Description GNU Libc current is affected by: Mitigation bypass. The impact is: Attacker may bypass ASLR using cache of thread stack and heap. The component is: glibc. NOTE: Upstream comments indicate "this is being treated as a non-security bug and no real threat. Affected range >=2.40-3 Fixed version Not Fixed EPSS Score 1.20% EPSS Percentile 86th percentile Description GNU Libc current is affected by: Re-mapping current loaded library with malicious ELF file. The impact is: In worst case attacker may evaluate privileges. The component is: libld. The attack vector is: Attacker sends 2 ELF files to victim and asks to run ldd on it. ldd execute code. NOTE: Upstream comments indicate "this is being treated as a non-security bug and no real threat. Affected range >=2.40-3 Fixed version Not Fixed EPSS Score 0.41% EPSS Percentile 74th percentile Description GNU Libc current is affected by: Mitigation bypass. The impact is: Attacker may bypass stack guard protection. The component is: nptl. The attack vector is: Exploit stack buffer overflow vulnerability and use this bypass vulnerability to bypass stack guard. NOTE: Upstream comments indicate "this is being treated as a non-security bug and no real threat. Affected range >=2.40-3 Fixed version Not Fixed EPSS Score 0.44% EPSS Percentile 75th percentile Description In the GNU C Library (aka glibc or libc6) through 2.29, check_dst_limits_calc_pos_1 in posix/regexec.c has Uncontrolled Recursion, as demonstrated by '(\227|)(\1\1|t1|\\2537)+' in grep. Affected range >=2.40-3 Fixed version Not Fixed EPSS Score 0.82% EPSS Percentile 82nd percentile Description The glob implementation in the GNU C Library (aka glibc or libc6) allows remote authenticated users to cause a denial of service (CPU and memory consumption) via crafted glob expressions that do not match any pathnames, as demonstrated by glob expressions in STAT commands to an FTP daemon, a different vulnerability than CVE-2010-2632.

systemd 256.7-1 (deb) pkg:deb/debian/[email protected]?os_distro=trixie&os_name=debian&os_version=unstable Affected range >=256.7-1 Fixed version Not Fixed EPSS Score 0.10% EPSS Percentile 42nd percentile Description An issue was discovered in systemd 253. An attacker can modify the contents of past events in a sealed log file and then adjust the file such that checking the integrity shows no error, despite modifications. NOTE: the vendor reportedly sent "a reply denying that any of the finding was a security vulnerability." Affected range >=256.7-1 Fixed version Not Fixed EPSS Score 0.10% EPSS Percentile 42nd percentile Description An issue was discovered in systemd 253. An attacker can truncate a sealed log file and then resume log sealing such that checking the integrity shows no error, despite modifications. NOTE: the vendor reportedly sent "a reply denying that any of the finding was a security vulnerability." Affected range >=256.7-1 Fixed version Not Fixed EPSS Score 0.09% EPSS Percentile 39th percentile Description An issue was discovered in systemd 253. An attacker can modify a sealed log file such that, in some views, not all existing and sealed log messages are displayed. NOTE: the vendor reportedly sent "a reply denying that any of the finding was a security vulnerability." Affected range >=256.7-1 Fixed version Not Fixed EPSS Score 0.04% EPSS Percentile 5th percentile Description systemd, when updating file permissions, allows local users to change the permissions and SELinux security contexts for arbitrary files via a symlink attack on unspecified files.

openldap 2.5.18+dfsg-3 (deb) pkg:deb/debian/[email protected]%2Bdfsg-3?os_distro=trixie&os_name=debian&os_version=unstable Affected range >=2.5.18+dfsg-3 Fixed version Not Fixed EPSS Score 0.16% EPSS Percentile 54th percentile Description libldap in certain third-party OpenLDAP packages has a certificate-validation flaw when the third-party package is asserting RFC6125 support. It considers CN even when there is a non-matching subjectAltName (SAN). This is fixed in, for example, openldap-2.4.46-10.el8 in Red Hat Enterprise Linux. Affected range >=2.5.18+dfsg-3 Fixed version Not Fixed EPSS Score 0.41% EPSS Percentile 74th percentile Description contrib/slapd-modules/nops/nops.c in OpenLDAP through 2.4.45, when both the nops module and the memberof overlay are enabled, attempts to free a buffer that was allocated on the stack, which allows remote attackers to cause a denial of service (slapd crash) via a member MODDN operation. Affected range >=2.5.18+dfsg-3 Fixed version Not Fixed EPSS Score 0.04% EPSS Percentile 10th percentile Description slapd in OpenLDAP 2.4.45 and earlier creates a PID file after dropping privileges to a non-root account, which might allow local users to kill arbitrary processes by leveraging access to this non-root account for PID file modification before a root script executes a "kill cat /pathname" command, as demonstrated by openldap-initscript. Affected range >=2.5.18+dfsg-3 Fixed version Not Fixed EPSS Score 0.42% EPSS Percentile 74th percentile Description The nss_parse_ciphers function in libraries/libldap/tls_m.c in OpenLDAP does not properly parse OpenSSL-style multi-keyword mode cipher strings, which might cause a weaker than intended cipher to be used and allow remote attackers to have unspecified impact via unknown vectors.

coreutils 9.4-3.1 (deb) pkg:deb/debian/[email protected]?os_distro=trixie&os_name=debian&os_version=unstable Affected range >=9.4-3.1 Fixed version Not Fixed EPSS Score 0.04% EPSS Percentile 5th percentile Description A flaw was found in the GNU coreutils "split" program. A heap overflow with user-controlled data of multiple hundred bytes in length could occur in the line_bytes_split() function, potentially leading to an application crash and denial of service. Affected range >=9.4-3.1 Fixed version Not Fixed EPSS Score 0.04% EPSS Percentile 5th percentile Description In GNU Coreutils through 8.29, chown-core.c in chown and chgrp does not prevent replacement of a plain file with a symlink during use of the POSIX "-R -L" options, which allows local users to modify the ownership of arbitrary files by leveraging a race condition. Affected range >=9.4-3.1 Fixed version Not Fixed EPSS Score 0.04% EPSS Percentile 5th percentile Description chroot in GNU coreutils, when used with --userspec, allows local users to escape to the parent session via a crafted TIOCSTI ioctl call, which pushes characters to the terminal's input buffer.

shadow 1:4.16.0-4 (deb) pkg:deb/debian/shadow@1:4.16.0-4?os_distro=trixie&os_name=debian&os_version=unstable Affected range >=1:4.16.0-4 Fixed version Not Fixed EPSS Score 0.04% EPSS Percentile 5th percentile Description shadow 4.8, in certain circumstances affecting at least Gentoo, Arch Linux, and Void Linux, allows local users to obtain root access because setuid programs are misconfigured. Specifically, this affects shadow 4.8 when compiled using --with-libpam but without explicitly passing --disable-account-tools-setuid, and without a PAM configuration suitable for use with setuid account management tools. This combination leads to account management tools (groupadd, groupdel, groupmod, useradd, userdel, usermod) that can easily be used by unprivileged local users to escalate privileges to root in multiple ways. This issue became much more relevant in approximately December 2019 when an unrelated bug was fixed (i.e., the chmod calls to suidusbins were fixed in the upstream Makefile which is now included in the release version 4.8). Affected range >=1:4.16.0-4 Fixed version Not Fixed EPSS Score 0.16% EPSS Percentile 52nd percentile Description initscripts in rPath Linux 1 sets insecure permissions for the /var/log/btmp file, which allows local users to obtain sensitive information regarding authentication attempts. NOTE: because sshd detects the insecure permissions and does not log certain events, this also prevents sshd from logging failed authentication attempts by remote attackers.

openssl 3.3.2-1 (deb) pkg:deb/debian/[email protected]?os_distro=trixie&os_name=debian&os_version=unstable Affected range >=3.2.2-1 Fixed version Not Fixed EPSS Score 0.07% EPSS Percentile 30th percentile Description OpenSSL 0.9.8i on the Gaisler Research LEON3 SoC on the Xilinx Virtex-II Pro FPGA uses a Fixed Width Exponentiation (FWE) algorithm for certain signature calculations, and does not verify the signature before providing it to a caller, which makes it easier for physically proximate attackers to determine the private key via a modified supply voltage for the microprocessor, related to a "fault-based attack." Affected range >=3.3.2-1 Fixed version Not Fixed EPSS Score 0.04% EPSS Percentile 11th percentile Description Issue summary: Use of the low-level GF(2^m) elliptic curve APIs with untrusted explicit values for the field polynomial can lead to out-of-bounds memory reads or writes. Impact summary: Out of bound memory writes can lead to an application crash or even a possibility of a remote code execution, however, in all the protocols involving Elliptic Curve Cryptography that we're aware of, either only "named curves" are supported, or, if explicit curve parameters are supported, they specify an X9.62 encoding of binary (GF(2^m)) curves that can't represent problematic input values. Thus the likelihood of existence of a vulnerable application is low. In particular, the X9.62 encoding is used for ECC keys in X.509 certificates, so problematic inputs cannot occur in the context of processing X.509 certificates. Any problematic use-cases would have to be using an "exotic" curve encoding. The affected APIs include: EC_GROUP_new_curve_GF2m(), EC_GROUP_new_from_params(), and various supporting BN_GF2m_*() functions. Applications working with "exotic" explicit binary (GF(2^m)) curve parameters, that make it possible to represent invalid field polynomials with a zero constant term, via the above or similar APIs, may terminate abruptly as a result of reading or writing outside of array bounds. Remote code execution cannot easily be ruled out. The FIPS modules in 3.3, 3.2, 3.1 and 3.0 are not affected by this issue.

gnupg2 2.2.44-1 (deb) pkg:deb/debian/[email protected]?os_distro=trixie&os_name=debian&os_version=unstable Affected range >=2.2.44-1 Fixed version Not Fixed EPSS Score 0.05% EPSS Percentile 18th percentile Description GnuPG can be made to spin on a relatively small input by (for example) crafting a public key with thousands of signatures attached, compressed down to just a few KB.

util-linux 2.40.2-9 (deb) pkg:deb/debian/[email protected]?os_distro=trixie&os_name=debian&os_version=unstable Affected range >=2.40.2-9 Fixed version Not Fixed EPSS Score 0.05% EPSS Percentile 18th percentile Description A flaw was found in the util-linux chfn and chsh utilities when compiled with Readline support. The Readline library uses an "INPUTRC" environment variable to get a path to the library config file. When the library cannot parse the specified file, it prints an error message containing data from the file. This flaw allows an unprivileged user to read root-owned files, potentially leading to privilege escalation. This flaw affects util-linux versions prior to 2.37.4.

tar 1.35+dfsg-3 (deb) pkg:deb/debian/[email protected]%2Bdfsg-3?os_distro=trixie&os_name=debian&os_version=unstable Affected range >=1.35+dfsg-3 Fixed version Not Fixed EPSS Score 0.69% EPSS Percentile 80th percentile Description Tar 1.15.1 does not properly warn the user when extracting setuid or setgid files, which may allow local users or remote attackers to gain privileges.

gnutls28 3.8.6-2 (deb) pkg:deb/debian/[email protected]?os_distro=trixie&os_name=debian&os_version=unstable Affected range >=3.8.6-2 Fixed version Not Fixed EPSS Score 0.60% EPSS Percentile 79th percentile Description The SSL protocol, as used in certain configurations in Microsoft Windows and Microsoft Internet Explorer, Mozilla Firefox, Google Chrome, Opera, and other products, encrypts data by using CBC mode with chained initialization vectors, which allows man-in-the-middle attackers to obtain plaintext HTTP headers via a blockwise chosen-boundary attack (BCBA) on an HTTPS session, in conjunction with JavaScript code that uses (1) the HTML5 WebSocket API, (2) the Java URLConnection API, or (3) the Silverlight WebClient API, aka a "BEAST" attack.

glib2.0 2.82.1-1 (deb) pkg:deb/debian/[email protected]?os_distro=trixie&os_name=debian&os_version=unstable Affected range >=2.82.1-1 Fixed version Not Fixed EPSS Score 0.16% EPSS Percentile 52nd percentile Description GLib 2.31.8 and earlier, when the g_str_hash function is used, computes hash values without restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted input to an application that maintains a hash table. NOTE: this issue may be disputed by the vendor; the existence of the g_str_hash function is not a vulnerability in the library, because callers of g_hash_table_new and g_hash_table_new_full can specify an arbitrary hash function that is appropriate for the application.
