HTTP::Date versions before 6.08 for Perl allow CPU exhaustion via polynomial regex backtracking in parse_date. parse_date() matches the date string against a chain of alternative regexes, and str2time() delegates to it. Several of these patterns place unbounded quantifiers next to each other before a trailing `\s*$` anchor. A valid date prefix followed by a long interior run of digits, letters, or whitespace and a single trailing byte that defeats the final match forces the engine to repartition the run, giving polynomial (about quadratic) backtracking. A header value of a few tens of kilobytes runs for tens of seconds of CPU. HTTP::Date parses timestamps such as HTTP `Date`, `Expires`, and `Last-Modified` headers, which commonly originate from untrusted sources. Any caller that passes an untrusted date header to str2time() or parse_date() can be driven to consume unbounded CPU, a denial of service.

The version of perl-HTTP-Date installed on the remote host is prior to 6.02-8. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2026-3996 advisory.

    parse_date() -- and str2time(), which delegates to it -- used regexes withambiguous adjacent greedy runs     (year/clock/timezone digits andtimezone/ASCII-timezone letters) before a trailing anchor. A valid-     lookingdate prefix followed by a long interior run of digits, letters, or whitespaceand a trailing junk     character forced O(N^2) backtracking, so a ~100 KB stringburned tens of seconds of CPU: a denial of     service.
