Microsoft Object Linking and Embedding (OLE) Automation WMF File Remote Code Execution Vulnerability

Risk

High

Date Discovered

June 14, 2011

Description

Microsoft Object Linking and Embedding (OLE) Automation is prone to a remote code-execution vulnerability because of an underflow error. An attacker can exploit this issue by enticing an unsuspecting user to view a malicious webpage or a specially crafted file. Successful exploits will allow the attacker to execute arbitrary code in the context of the user running the application, which can compromise the application and possibly the computer.

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.
