{"id":"DEBIAN-CVE-2026-60074","details":"Date::Manip versions through 7.00 for Perl return corrupted dates via non-ASCII decimal digits that pass the numeric range tests in check.  The parse regexes capture year, month and day with the `\\d` shorthand, which on a character string matches the whole Unicode decimal digit property `\\p{Nd}` and not just `[0-9]`. Date::Manip::Base::check then validates the captured fields with numeric comparisons alone (`$y\u003c1 || $y\u003e9999`, `$m\u003c1 || $m\u003e12`, `$d\u003c1 || $d\u003e$days`), and _parse_check stores the numified fields (`$y+0`). Perl truncates a string at the first character that is not an ASCII digit, so a field whose leading characters are ASCII digits numifies to an in-range prefix and satisfies every test: a year field of three ASCII digits followed by U+0664 ARABIC-INDIC DIGIT FOUR numifies to 202, giving the year 0202, and one non-ASCII digit in the month or day field shifts those fields the same way. The hour, minute and second fields match explicit ASCII character classes (`0?[0-9]`, `[0-5][0-9]`) and do not shift, though a non-ASCII digit in a fractional hour or minute field truncates the fraction.  Any caller that passes an untrusted character string to ParseDate() or Date::Manip::Date-\u003eparse() can get back a date that differs from the string it parsed, with no parse error. Where the parsed date gates logic such as an expiry check or a retention window, the shift goes unnoticed.","modified":"2026-09-14T17:03:46.853743559Z","published":"2026-07-30T14:17:02.587Z","upstream":["CVE-2026-60074"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2026-60074"}],"affected":[{"package":{"name":"libdate-manip-perl","ecosystem":"Debian:12","purl":"pkg:deb/debian/libdate-manip-perl?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["6.91-1","6.92-1","6.93-1","6.94-1","6.95-1","6.96-1","6.97-1","6.98-1","6.99-1","6.99-2","7.00-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-60074.json"}},{"package":{"name":"libdate-manip-perl","ecosystem":"Debian:13","purl":"pkg:deb/debian/libdate-manip-perl?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["6.98-1","6.99-1","6.99-2","7.00-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-60074.json"}},{"package":{"name":"libdate-manip-perl","ecosystem":"Debian:14","purl":"pkg:deb/debian/libdate-manip-perl?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"6.99-2"}]}],"versions":["6.98-1","6.99-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2026-60074.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
