CVE-2022-4976Network attack vector

Arbitrary code execution via bundled Info-ZIP overflows

Published Jun 12, 2025 · Updated Jun 13, 2025

Memory corruption in Archive::Unzip::Burst 0.01 through 0.09 allows attackers to execute code through a crafted ZIP archive. Its bundled Info-ZIP code performs unsafe heap operations during CRC32 verification and in test_compr_eb and getZip64Data while parsing archive data. A consuming Perl process must extract attacker-controlled content; published evidence does not establish which inherited paths are reachable through the wrapper.
