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 11-301 - 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 way Adobe handles PICT images. When Adobe parses a PICT image containing an 0x0E opcode and it is read the following word in the file will be interpreted as a loop counter that copies data from the file into a heap buffer that has been created using the height and with of the picture. The resulting heap overflow can result in remote code execution under the rights of the current user.
