Update Summary

USN-8736-1 updates Perl for Ubuntu Server 26.04 LTS (Resolute Raccoon) to address two security issues, including out-of-bounds heap reads or writes and regex matching bypasses. The fixed package versions are 5.40.1-7ubuntu0.2. Reference IDs: CVE-2026-15534, CVE-2026-19487.

Update Details

Security

  • Perl fixed an issue where large inputs during regular expression matching could trigger out-of-bounds heap reads or writes, potentially leading to denial of service or arbitrary code execution (CVE-2026-15534).
  • Perl fixed an issue in regular expressions with alternative matching branches that could cause incorrect matches and allow security restrictions to be bypassed (CVE-2026-19487).

Hints

  • A standard system update installs the required fixes.
  • For Ubuntu Server 26.04 LTS, update to libperl-dev, libperl5.40, perl-base, and perl-debug version 5.40.1-7ubuntu0.2.
