Symantec Anti-virus Software Open To Attack?

Gregg Keizer writes in TechWeb News:

Symantec's line of anti-virus software is vulnerable to attack, a prominent security researcher revealed Tuesday. The bug is currently unpatched, although Symantec has issued an advisory.

The vulnerability, which was discovered and reported by Alex Wheeler, is in how Symantec's AntiVirus Library, part of all the Cupertino, Calif.-based security giant's anti-virus products, handles RAR compressed files. RAR files are created by the WinRAR compression utility, developed and sold by RarLab.

The bug, labeled as "Highly critical" by Danish vulnerability tracker Secunia and "High" by Symantec itself, can cause a heap overflow, which then may let an attacker execute additional code. Bottom-line: the bug could result in a completely compromised machine.
