Date Discovered April 13, 2010
Description Adobe Acrobat and Reader are prone to a heap-based buffer-overflow vulnerability because they fail to properly validate user-supplied input.
Attackers can exploit this issue to execute arbitrary code in the context of the user running the application. Failed exploit attempts will result in a denial of service.
The following products are affected:
Adobe Reader 9.3.1 and prior for Windows, Macintosh, and UNIX
Adobe Acrobat 9.3.1 and prior for Windows and Macintosh
Adobe Reader 8.2.1 and prior for Windows and Macintosh
Acrobat 8.2.1 and prior for Windows and Macintosh
Note: This vulnerability was previously documented in BID 39329 (Adobe Acrobat and Reader April 2010 Multiple Remote Vulnerabilities) but has been given its own record to better document the issue.

Block external access at the network boundary, unless external parties require service. If global access isn't needed, filter access to the affected computer at the network boundary. Restricting access to only trusted computers and networks might greatly reduce the likelihood of a successful exploit.
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.
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.
