Title: Apple PSNormalizer PostScript Buffer Overflow Vulnerability
Severity: HIGH
Description:
PSNormalizer is an application for processing PostScript files.
PSNormalizer is prone to a buffer-overflow vulnerability that arises when the application handles specially crafted PostScript files. Specifically, the issue is caused by PSNormalizer's handling of the bounding-box comment in PostScript files.
An attacker can exploit this issue to execute arbitrary code within the context of the affected application. Failed exploit attempts will result in a denial-of-service condition.
The following versions are affected:
Mac OS X v10.4.11 and prior
Mac OS X Server v10.4.11 and prior
