CVE-2012-2852: Use After Free
First published: Mon Aug 06 2012(Updated: )
The PDF functionality in Google Chrome before 21.0.1180.57 on Mac OS X and Linux, and before 21.0.1180.60 on Windows and Chrome Frame, does not properly handle object linkage, which allows remote attackers to cause a denial of service (use-after-free) or possibly have unspecified other impact via a crafted document.
