CVE-2025-15649: IO::Uncompress::Unzip versions before 2.215 for Perl propagate uncaught exception when parsing zip header with malformed DOS date

• Severity: medium (CVSS 5.5 v3.1)
• Exploited in the wild: not listed in CISA KEV
• EPSS: 0.1% probability of exploitation in the next 30 days
• Public exploit or detection template: none known
• Published: 2026-05-27 · updated 2026-07-24
• Weakness: CWE-248

Description

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.
