Adobe Reader 9.4 Remote Memory Corruption Vulnerability



Date Discovered

November 4, 2010


Adobe Reader is prone to a remote memory-corruption vulnerability. Successful exploits may allow attackers to execute arbitrary code in the context of the user running the affected application. Failed exploit attempts will result in a denial-of-service condition. Adobe Reader versions 9.4.0 and 8.1.7 are affected; other versions may also be vulnerable.

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 limit exposure to these and other latent vulnerabilities, never handle files that originate from unfamiliar or untrusted sources.

Do not follow links provided by unknown or untrusted sources.
To reduce the likelihood of attacks, never visit sites of questionable integrity or follow links provided by unfamiliar or untrusted sources.

Disable any unneccessary default services.
Disable JavaScript in the affected application to prevent exploit of this issue.

Implement multiple redundant layers of security.
As an added precaution, deploy memory-protection schemes (such as nonexecutable stack/heap configuration and randomly mapped memory segments). This may complicate exploits of memory-corruption vulnerabilities.

Run all software as a nonprivileged user with minimal access rights.
To reduce the impact of latent vulnerabilities, run applications with the minimal amount of privileges required for functionality.

Updates are available. Please see the references for more information.
