Medium (5.5). EPSS 0.1% chance of exploitation in the next 30 days.
IO::Uncompress::Unzip versions before 2.215 for Perl propagate uncaught exception when parsing zip header with malformed DOS date.
_dosToUnixTime() decodes the local-file-header last-modification date field and calls Time::Local::timelocal() without an eval guard. A header whose date field decodes to an out-of-range month, day, or hour causes timelocal() to die.
The exception propagates out of IO::Uncompress::Unzip->new($file) where callers expect undef plus $UnzipError.
