Name of the Vulnerable Software and Affected Versions: APT versions prior to 2.1.2

Description: The issue is related to missing input validation in the ar/tar implementations, which could result in denial of service when processing specially crafted deb files. This could allow a remote attacker to cause a denial of service.

Recommendations: For versions prior to 2.1.2, update to version 2.1.2 or later to resolve the issue. As a temporary workaround, consider restricting the use of specially crafted deb files until a patch is available.
