IO-Compress supports reading and writing of bzip2, RFC 1950, RFC 1951, RFC 1952 (i.e. gzip) and zip files/buffers. The following modules used to be distributed separately, but are now included with the IO-Compress distribution:

  • Compress-Zlib
  • IO-Compress-Zlib

  • IO-Compress-Base

Security Fix(es):

  • perl-IO-Compress: perl-IO-Compress: Arbitrary code execution via attacker-controlled output glob (CVE-2026-48962)
