Amazon Linux 2027 Preview Security Advisory: ALAS2027-2026-198
Advisory Release Date: 2026-10-12 09:00 Pacific
Advisory Updated Date: 2026-10-20 15:48 Pacific
Severity:
Medium
Issue Overview:
Package updates are available for Amazon Linux 2027 that fix the following vulnerabilities:
CVE-2026-14741:
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.
