  * CVE-2026-3219: pip doesn't reject concatenated ZIP (bsc#1262429).
  * CVE-2026-3276: quadratic complexity in `unicodedata.normalize()` can lead to
    DoS when processing specially crafted Unicode input (bsc#1267581).
  * CVE-2026-4360: in the Tarfile.extract() function, the filter parameter is
    not passed properly when extracting hardlinks (bsc#1269959).
  * CVE-2026-7774: `tarfile.data_filter` path traversal bypass allows writing
    outside the extraction directory (bsc#1267821).
  * CVE-2026-11972: infinite loop due to improper EOF handling in the tarfile
    module streaming mode can lead to DoS (bsc#1269788).
  * CVE-2026-13346: Arbitrary file installation via malicious package indexes
    (bsc#1273090 bsc#1273091 bsc#1273094).
  * CVE-2026-15308: Incremental HTMLParser allows CPU-exhaustion DoS via
    repeated unterminated markup declarations (bsc#1271192).

Non security issues fixed:

  * crypto-policies: Extend the crypto-policies support for mozilla-nss,
    openjdk, krb5, bind, stunnel, openssh, libssh and more packages
