Hi,
The following vulnerability was published for libio-compress-perl.
CVE-2026-48961[0]:
| IO::Compress versions from 2.207 before 2.220 for Perl ship a
| zipdetails CLI tool that crashes with undefined subroutine on Info-
| ZIP Unix Extra Field with 8-byte UID or GID. When decode_ux() in
| bin/zipdetails handles an Info-ZIP Unix Extra Field (tag 0x7875)
| with UID Size or GID Size set to 8, causing zipdetails to decode an
| 8-byte UID or GID value, it dispatches through decodeLitteEndian(),
| which calls a misnamed helper unpackValueQ. The actual function
| defined in the same file is unpackValue_Q (with underscore); the
| call raises 'Undefined subroutine &main::unpackValueQ' and the
| script exits with status 255. Library callers of IO::Compress and
| IO::Uncompress are not affected; the defect is in the bundled CLI
| tool.
If you fix the vulnerability please also make sure to include the
CVE (Common Vulnerabilities & Exposures) id in your changelog entry.
