CVE-2024-48615Public exploitNetwork attack vector

bsdtar crash via truncated PAX archive

Published Mar 28, 2025 · Updated Apr 1, 2025

Null pointer dereference in libarchive 3.7.5 through 3.7.6 allows remote attackers to crash bsdtar with a truncated PAX archive. In header_pax_extension, __archive_read_ahead can return NULL for truncated input, but the code checks did_read and dereferences the returned pointer while parsing a PAX attribute name. Processing an attacker-supplied archive is required, and the demonstrated consequence is termination of the bsdtar process without reported data access or modification.
