Adobe Illustrator Encapsulated Postscript File Remote Buffer Overflow Vulnerability

Risk

High

Date Discovered

December 2, 2009

Description

Adobe Illustrator is prone to a remote buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied data. An attacker can exploit this issue by enticing an unsuspecting victim to open a malicious Encapsulated PostScript file. Successfully exploiting this issue will allow attackers to execute arbitrary code with the privileges of the user running the affected application. Failed exploit attempts will likely result in a denial-of-service condition. This issue affects Illustrator CS4 14.0.0 and CS3 13.0.0; other versions may also be affected.

Technologies Affected

  • Adobe Illustrator CS3
  • Adobe Illustrator CS4

Recommendations

Do not accept or execute files from untrusted or unknown sources.

Malicious files may be hosted on a webpage or sent via email, instant messaging, or other means. Never accept or open any files that originate from an untrusted source.

Do not follow links provided by unknown or untrusted sources.

Web users should be cautious about following links to sites that are provided by unfamiliar or suspicious sources. Filtering HTML from emails may help remove a possible vector for transmitting malicious links to users.

Implement multiple redundant layers of security.

Since this issue may be leveraged to execute code, we recommend memory-protection schemes, such as nonexecutable stack/heap configurations and randomly mapped memory segments. This tactic 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, always run nonadministrative software as an unprivileged user with minimal access rights.
Vendor updates are available. Please see the references for more information.
