Multiple Adobe products are prone to a buffer-overflow vulnerability because they fail to perform adequate boundary checks on user-supplied input. The vulnerability occurs when handling malformed image header data in image files. Successfully exploiting this issue allows attackers to execute arbitrary code with the privileges of a user running one of the applications. Failed exploit attempts will result in a denial-of-service condition. The following products are vulnerable: Adobe Photoshop Album Starter 3.2 Adobe After Effects CS3 Other applications and versions may also be affected.
- Adobe After Effects CS3
- Adobe Photoshop Album Starter 3.2
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 exploits, never handle files that originate from 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 this vulnerability to execute arbitrary code.
Adobe has released an advisory stating that they are working on fixes to address this issue. This BID previously stated that Adobe Photoshop CS3 was affected, but Adobe states that their previous advisory (APSB07-13) addresses this issue for Photoshop CS2, Photoshop CS3, and Photoshop Elements 5.0. Please see the references for more information.
