Red Hat Security Advisory 2011-1434-01 - This update fixes multiple security flaws in Adobe Reader. A PDF file with an embedded, specially-crafted SWF file could cause Adobe Reader to crash or, potentially, execute arbitrary code as the user running Adobe Reader when opened. A flaw in Adobe Flash Player could allow an attacker to conduct cross-site scripting (XSS) attacks if a victim were tricked into visiting a specially-crafted web page. Various other issues were also addressed.

Zero Day Initiative Advisory 11-296 - This vulnerability allows remote attackers to execute arbitrary code on vulnerable installations of Adobe Reader. User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the Adobe Image parsing library. When Adobe Reader tries to parse an malformed .BMP image containing Run Length Encoded data it fails to perform sufficient boundary checks on the data. The effect can be a heap buffer overflow resulting in remote code execution under the context of the current user.
