The following vulnerability was published[0] for IO-Compress:

  CVE ID:  CVE-2025-15649
  Distribution:  IO-Compress
  Versions:  before 2.215

  MetaCPAN:  https://metacpan.org/dist/IO-Compress
  VCS Repo:  https://github.com/pmqs/IO-Compress

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

  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.

This CPAN module is shipped in both libio-compress-perl and perl. The
libio-compress-perl package was already fixed for sid + forky in version
2.215-1.

Copying the libio-compress-perl maintainers, and Salvatore for his security
hat. Not sure if we want to track this separately for the libio-compress-perl
package at this point. Feel free to clone this bug if it helps.
