Mac has got its own PDF exploit fix in a new security update, it’s the same as the iOS 4.0.2 for iPhone / iPod Touch, and iOS 3.2.2 for iPad which fixes PDF exploit that was discovered when JailbreakMe released! Here’s what Apple says about the security update.
Impact: Viewing or downloading a document containing a maliciously crafted embedded font may lead to arbitrary code execution
Description: A stack buffer overlow exists in Apple Type Services’ handling of embedded fonts. Viewing or downloading a document containing a maliciously crafted embedded font may lead to arbitrary code execution. This issue is addressed through improved bounds checking.
