Microsoft Windows Cinepak Codec Media Decompression Remote Code Execution Vulnerability

Risk

High

Date Discovered

August 10, 2010

Description

Microsoft Windows is prone to a remote code-execution vulnerability when handling compressed media files. An attacker can exploit this issue by enticing an unsuspecting user to open a malicious file or visit a website containing malicious streaming media content. A successful exploit may allow arbitrary code to run in the context of the currently logged-in user.

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.

Various memory-protection schemes (such as nonexecutable and randomly mapped memory segments) may hinder an attacker's ability to exploit memory corruption vulnerabilities to execute arbitrary code. Host-based intrusion-prevention systems may also help prevent exploits.
Updates are available; please see the references for more information.
