Avira AntiVir File Handling Vulnerabilities

critical Nessus Plugin ID 25348

Synopsis

The remote Windows host contains an application that is affected by multiple issues.

Description

The remote host is running Avira AntiVir, an antivirus software application.

The version of AntiVir installed on the remote host is reportedly prone to a buffer overflow in its LZH file processing code as well as denial of service vulnerabilities when parsing UPX and TAR files. An attacker may be able to exploit these issues to execute arbitrary code on the remote host, likely with LOCAL SYSTEM privileges, to crash the remote antivirus engine, or to cause the CPU to enter an endless loop.

Solution

Use AntiVir's Update feature to upgrade to the latest version.
