Title: Avast! Antivirus RAR File Scan Evasion Vulnerability
Severity: HIGH
Description:
Avast! Antivirus is an application that provides virus protection.
The product's scan engine is prone to a vulnerability that may allow certain compressed archives to go undetected. The vulnerability occurs because the software fails to properly inspect specially crafted 'RAR' files.
Successful exploits will allow attackers to distribute files containing malicious code that the antivirus application will fail to detect.
