• full diff: golang/go@go1.21.10...go1.21.11

From the security announcement;

We have just released Go versions 1.22.4 and 1.21.11, minor point releases. These minor releases include 2 security fixes following the security policy:

• archive/zip: mishandling of corrupt central directory record

  The archive/zip package's handling of certain types of invalid zip files
  differed from the behavior of most zip implementations. This misalignment
  could be exploited to create an zip file with contents that vary depending
  on the implementation reading the file. The archive/zip package now rejects
  files containing these errors.

  Thanks to Yufan You for reporting this issue.

  This is CVE-2024-24789 and Go issue https://go.dev/issue/66869.

• net/netip: unexpected behavior from Is methods for IPv4-mapped IPv6 addresses

  The various Is methods (IsPrivate, IsLoopback, etc) did not work as expected
  for IPv4-mapped IPv6 addresses, returning false for addresses which would
  return true in their traditional IPv4 forms.

  Thanks to Enze Wang of Alioth and Jianjun Chen of Zhongguancun Lab
  for reporting this issue.

  This is CVE-2024-24790 and Go issue https://go.dev/issue/67680.
