Description

A flaw was found in libarchive. This vulnerability allows a remote attacker to trigger a heap overflow by providing a specially crafted tar archive.

Successful exploitation could lead to a denial of service, making the system unavailable, or potentially allow for arbitrary code execution, giving the attacker control over the affected system.
