hankwang writes: Security researcher Petko Petkov, who is known for his recent discovery of a vulnerability with Quicktime in Firefox, claims to have discovered an exploit that allows arbitrary code execution when a maliciously crafted PDF document is opened in any version of Adobe Reader. Petkov did not disclose any technical details other than a video, but claims on his blog that Adobe has acknowledged the vulnerability. If this exploit goes wild, it could cause some serious problems, as PDFs are usually automatically opened from web browsers and widely used and trusted by corporate users.
