Vulnerability Note VU#324929

McAfee VirusScan Enterprise heap buffer overflow vulnerability

Overview

The McAfee VirusScan progream contains a buffer overflow vulnerability. If exploited, this vulnerability may allow an attacker to arbitrary execute code.

I. Description

McAfee VirusScan Enterprise includes an anti-virus, firewall, and host-based intrusion protection system.

The on-demand virus scanner component of McAfee VirusScan Enterprise contains a heap buffer overflow vulnerability. This vulnerability occurs because the scanner fails to properly process files with long file names that contain multi-byte characters.

Note that per McAfee Security Bulletin 612750:

    In order for this attack to work, the target computer must have East Asia language files installed, and the default Unicode codepage must be set to a language which contains multi-byte characters--such as Chinese.

II. Impact

A remote, unauthenticated attacker may be able to execute arbitrary code with SYSTEM privileges or create a denial-of-service condition.

III. Solution

Update

McAfee has released VirusScan Enterprise 8.0i patch 12 to address this issue. See McAfee Security Bulletin 612750 for instructions on how to install this update directly or through McAfee's ePolicy Orchestrator.
