{"id":"UBUNTU-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":"2026-09-16T14:01:53.194224624Z","published":"2026-07-30T14:17:00Z","upstream":["CVE-2026-60074"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-60074"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-60074"},{"type":"REPORT","url":"https://lists.security.metacpan.org/cve-announce/msg/42266594/"},{"type":"REPORT","url":"https://security.metacpan.org/patches/D/Date-Manip/6.99/CVE-2026-60074-r1.patch"}],"affected":[{"package":{"name":"libdate-manip-perl","ecosystem":"Ubuntu:14.04:LTS","purl":"pkg:deb/ubuntu/libdate-manip-perl?arch=source&distro=trusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["6.40-1","6.41-1","6.42-1"],"ecosystem_specific":{"binaries":[{"binary_version":"6.42-1","binary_name":"libdate-manip-perl"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-60074.json"}},{"package":{"name":"libdate-manip-perl","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/libdate-manip-perl?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["6.50-1","6.51-1","6.52-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libdate-manip-perl","binary_version":"6.52-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-60074.json"}},{"package":{"name":"libdate-manip-perl","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/libdate-manip-perl?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["6.59-1","6.60-1"],"ecosystem_specific":{"binaries":[{"binary_version":"6.60-1","binary_name":"libdate-manip-perl"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-60074.json"}},{"package":{"name":"libdate-manip-perl","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/libdate-manip-perl?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["6.78-1","6.79-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libdate-manip-perl","binary_version":"6.79-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-60074.json"}},{"package":{"name":"libdate-manip-perl","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/libdate-manip-perl?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["6.85-1","6.86-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libdate-manip-perl","binary_version":"6.86-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-60074.json"}},{"package":{"name":"libdate-manip-perl","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/libdate-manip-perl?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["6.92-1","6.93-1","6.94-1","6.95-1"],"ecosystem_specific":{"binaries":[{"binary_version":"6.95-1","binary_name":"libdate-manip-perl"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-60074.json"}},{"package":{"name":"libdate-manip-perl","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/libdate-manip-perl?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["6.98-1"],"ecosystem_specific":{"binaries":[{"binary_version":"6.98-1","binary_name":"libdate-manip-perl"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-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"},{"type":"Ubuntu","score":"medium"}]}
