Name of the Vulnerable Software and Affected Versions Avira Antivir Antivirus versions prior to 7.03.00.09

Description The issue is related to a buffer overflow in the file parsing engine, which can be triggered by a crafted LZH archive file. This is caused by an "integer cast around," allowing remote attackers to execute arbitrary code.

Recommendations For versions prior to 7.03.00.09, update to version 7.03.00.09 or later to resolve the issue. As a temporary workaround, consider restricting the handling of LZH archive files until the update is applied.
