Name: samba
CVEs: CVE-2021-44142, CVE-2022-1615
CVSSs: 8.8, 5.5
Action Needed: update to >= 4.17.5

Summary:

  • CVE-2021-44142: The Samba vfs_fruit module uses extended file attributes (EA, xattr) to provide "...enhanced compatibility with Apple SMB clients and interoperability with a Netatalk 3 AFP fileserver." Samba versions prior to 4.13.17, 4.14.12 and 4.15.5 with vfs_fruit configured allow out-of-bounds heap read and write via specially crafted extended file attributes. A remote attacker with write access to extended file attributes can execute arbitrary code with the privileges of smbd, typically root.
  • CVE-2022-1615: In Samba, GnuTLS gnutls_rnd() can fail and give predictable random values.

See also https://security.gentoo.org/glsa/202309-06.
(Note: That GLSA entry has 34 different CVEs, but only 2 affects Flatcar. In most cases they affect smbd, AD & DC, which are disabled in Flatcar. However, there were actually 2 rare cases that affect Flatcar, one in a vfs module, the other in lib.)
