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

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.

Security readout for executives and security teams

This flaw can crash Perl software that opens a specially malformed ZIP file through IO::Uncompress::Unzip before version 2.215. It is primarily an availability risk, not a data theft or code execution issue. Business urgency depends on whether affected Perl code processes ZIP files from users, partners, or automated ingestion pipelines. Exposure is most likely in Perl applications, batch jobs, or services using IO-Compress / IO::Uncompress::Unzip before 2.215 to parse ZIP files. Risk is higher when archives come from untrusted users, external partners, shared directories, or automated file intake. Treat this as a targeted availability fix. It should be scheduled promptly for file-processing systems, especially upload and ingestion paths, but it is not supported by sources as a breach-enabling or actively exploited vulnerability. Mitigation focus: Upgrade IO-Compress / IO::Uncompress::Unzip to version 2.215 or later.; Prioritize systems that parse ZIP files from users, partners, or automated intake paths.; If upgrading is delayed, restrict untrusted ZIP processing in affected Perl workflows..
