## Description:

This update for python311 fixes the following issues:

python311 was updated from version 3.11.10 to 3.11.13:

  * Security issues fixed:

  * CVE-2025-4516: Fixed blocking DecodeError handling vulnerability, which
    could lead to DoS (bsc#1243273).

  * CVE-2024-12718, CVE-2025-4138, CVE-2025-4330, CVE-2025-4517: Fixed multiple
    issues that allowed tarfile extraction filters to be bypassed using crafted
    symlinks and hard links (bsc#1244056, bsc#1244059, bsc#1244060, bsc#1244032)

  * Other changes and bugs fixed:

  * Improved handling of system call failures that OpenSSL reports (bsc#1241067)

  * Disable GC during thread operations to prevent deadlocks.
  * Fixed a potential denial of service vulnerability in the imaplib module.
  * Fixed bugs in the in the folding of rfc2047 encoded-words and in the folding
    of quoted strings when flattening an email message using a modern email
    policy.
  * Fixed parsing long IPv6 addresses with embedded IPv4 address.
  * Fixed ipaddress.IPv6Address.reverse_pointer output according to RFC 3596
  * Improved the textual representation of IPv4-mapped IPv6 addresses in
    ipaddress.
  * ipaddress: fixed hash collisions for IPv4Network and IPv6Network objects
  * os.path.realpath() now accepts a strict keyword-only argument.
  * Stop the processing of long IPv6 addresses early in ipaddress to prevent
    excessive memory consumption and a minor denial-of-service.
  * Updated bundled libexpat to 2.7.1
  * Writers of CPython documentation can now use next as the version for the
    versionchanged, versionadded, deprecated directives.
