Date Discovered April 28, 2007
Description Multiple image editors are prone to a remote buffer-overflow vulnerability because the software fails to properly bounds-check user-supplied input before copying it to an insufficiently sized memory buffer.
Successful exploits allow remote attackers to execute arbitrary machine code in the context of a vulnerable application. Failed exploit attempts likely result in denial-of-service conditions.
The following are vulnerable:
Adobe Photoshop CS2, CS3, and Elements 5.0
Corel Paint Shop Pro 11.20
Other versions may also be affected.
- Adobe GoLive 9
- Adobe Illustrator CS3
- Adobe Photoshop CS2
- Adobe Photoshop CS3
- Adobe Photoshop Elements 5.0
- Corel Paint Shop Pro Photo 11.20
Run all software as a nonprivileged user with minimal access rights. Run all software as a non-administrative user with the least amount of privileges required to successfully operate. This will lessen the potential damage that successful exploits may achieve.
Deploy network intrusion detection systems to monitor network traffic for malicious activity. Deploy NIDS to monitor network traffic for
anomalous or suspicious activity. Monitor logs generated by NIDS and by the server itself for evidence of attacks against the server.
Do not accept or execute files from untrusted or unknown sources. Users should not accept or execute files provided by untrusted or unknown sources.
Implement multiple redundant layers of security.
Various memory-protection schemes (such as non-executable and randomly mapped memory segments) may hinder an attacker's ability to exploit this vulnerability to execute arbitrary code.
Updates are available to address this issue. Please see the referenced advisories for more information.
