Date::Manip versions through 7.00 for Perl return corrupted dates via non-ASCII decimal digits that pass the numeric range tests in check
Vulnerability Description
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<1 || $y>9999`, `$m<1 || $m>12`, `$d<1 || $d>$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->parse() 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.

Vulnerability Title
SBECK Date::Manip 输入验证错误漏洞
Vulnerability Description
SBECK Date::Manip是SBECK个人开发者开源的一个日期处理模块。 SBECK Date::Manip 6.99及之前版本存在输入验证错误漏洞,该漏洞源于正则表达式使用\d简写匹配Unicode十进制数字而非仅ASCII数字,且验证仅用数值比较,导致非ASCII数字通过检查并返回错误日期。
