Summary
libarchive from version v3.2.0 onwards (commit 9693801580c0cf7c70e862d305270a16b52826a7) contains a CWE-20: Improper Input Validation vulnerability in the WARC parser - libarchive/archive_read_support_format_warc.c, _warc_read() that can result in DoS - quasi-infinite run time and disk usage from tiny file. The attack requires the victim to open a specially crafted WARC file.
Risk Assessment
An attacker can cause system overload (DoS) by opening a malicious WARC file, potentially leading to resource exhaustion and service unavailability.
Recommendation
Update libarchive to a version containing the fix or avoid opening untrusted WARC files.
