Microsoft Windows ASX File Parsing Remote Buffer Overflow Vulnerability

Risk

High

Date Discovered

February 14, 2012

Description

Microsoft Windows is prone to a remote buffer-overflow vulnerability when handling a specially crafted media file. An attacker can exploit this issue by enticing an unsuspecting user to view a webpage containing malicious content or to open a malicious media file. Successful exploits will allow the attacker to execute arbitrary code in the context of the currently logged-in user. Failed exploit attempts will likely result in denial-of-service conditions.

Recommendations

Run all software as a nonprivileged user with minimal access rights.

To reduce the impact of latent vulnerabilities, always run nonadministrative software as an unprivileged user with minimal access rights.

Deploy network intrusion detection systems to monitor network traffic for malicious activity.

Deploy NIDS to monitor network traffic for signs of anomalous or suspicious activity. This includes but is not limited to requests that include NOP sleds and unexplained incoming and outgoing traffic. This may indicate exploit attempts or activity that results from a successful exploit.

Do not accept or execute files from untrusted or unknown sources.

To reduce the likelihood of successful attacks, never handle or open files from unknown sources.

Do not follow links provided by unknown or untrusted sources.

To reduce the likelihood of successful exploits, never visit sites of questionable integrity or follow links provided by unfamiliar or untrusted sources.

Implement multiple redundant layers of security.

As this issue may be cause by a memory-corruption error, consider various memory-protection schemes (such as nonexecutable and randomly mapped memory segments) that may hinder an attacker's ability to exploit memory-corruption vulnerabilities. Host-based intrusion-prevention systems may also help prevent exploits.
Vendor updates are available. Please see the references for more information.
