Amazon Linux 2023 Security Advisory: ALAS2023-2026-3210
Advisory Released Date: 2026-10-12
Advisory Updated Date: 2026-10-12
Severity:
Medium
Issue Overview:
parse_date() -- and str2time(), which delegates to it -- used regexes with
ambiguous adjacent greedy runs (year/clock/timezone digits and
timezone/ASCII-timezone letters) before a trailing anchor. A valid-looking
date prefix followed by a long interior run of digits, letters, or whitespace
and a trailing junk character forced O(N^2) backtracking, so a ~100 KB string
burned tens of seconds of CPU: a denial of service. (CVE-2026-14741)
Affected Packages:
perl-HTTP-Date
Issue Correction:
Run dnf update perl-HTTP-Date --releasever 2023.12.20261012 or dnf update --advisory ALAS2023-2026-3210 --releasever 2023.12.20261012 to update your system.
