Summary

Important: perl-Date-Manip security update

Details

Date::Manip is a series of modules designed to make any common date/time operation easy to do. Operations such as comparing two times, determining a data a given amount of time from another, or parsing international times are all easily done. It deals with time as it is used in the Gregorian calendar (the one currently in use) with full support for time changes due to daylight saving time.

Security Fix(es):

perl-Date-Manip: Date::Manip for Perl: Denial of Service via CPU exhaustion in date parsing (CVE-2026-60075)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

CVE-2026-60075 (GCVE-0-2026-60075)

Vulnerability from cvelistv5 – Published: 2026-07-30 13:42 – Updated: 2026-08-21 08:18

Title

Date::Manip versions through 6.99 for Perl allow CPU exhaustion via quadratic backtracking in the unanchored time substitution in _parse_time

Summary

Date::Manip versions through 6.99 for Perl allow CPU exhaustion via quadratic backtracking in the unanchored time substitution in _parse_time. _parse_time removes a time from anywhere in the string with the unanchored substitution `s/$timerx/ /`, where $timerx is an auto-generated alternation of time patterns reached through a leading `(?:$atrx|^|\s+)`. The engine therefore retries the match at every position of an interior whitespace run: at each start position the leading `\s+` consumes the rest of the run greedily, the time alternation fails because the run holds no digits, and the engine backtracks a space at a time across the run before advancing the start position, which is quadratic in the length of the run. No time need be present in the string for this to happen, only a long run of whitespace, and the parse time rises about fourfold for each doubling of the run: a few kilobytes of whitespace costs seconds of CPU per parse and tens of kilobytes costs minutes. Any caller that passes an untrusted string of unbounded length to ParseDate(), Date::Manip::Date->parse() or ->parse_time() can be made to spend unbounded CPU in a single parse, a denial of service.
