Description Zack Miele 2024-05-22 13:54:34 UTC

A heap-based buffer overflow flaw was found in the rar e8 filter in libarchive. An attacker could trick a user into opening a specially crafted rar archive to induce a denial of service or arbitrary code execution in the context of the application using libarchive.
