CVE-2024-37407Public exploitNetwork attack vector

Out-of-bounds read via empty ZIP filename

Published Jun 8, 2024 · Updated Mar 14, 2025

Out-of-bounds read in libarchive before 3.7.4 allows attackers to read memory via a crafted ZIP archive processed with mac-ext enabled. The slurp_central_directory function reads name[tmp_length - 1] without first ensuring that the ZIP entry filename length is nonzero. The archive must contain an empty filename and be read with mac-ext; the upstream proof of concept observes the invalid read but reports no sanitizer-detected crash.
