In short
Adobe Reader and Acrobat versions 9, 10, and 11 contain a memory corruption flaw that allows attackers to run malicious code or crash the application by opening a specially crafted document. This is a critical vulnerability because these are widely used applications for viewing PDF files.
Technical detail
Out-of-bounds write vulnerability (CWE-787) in Adobe Reader/Acrobat 9.x, 10.x, and 11.x triggered via unspecified vectors in PDF processing. Exploitation requires user interaction (opening a malicious PDF), but results in arbitrary code execution with application privileges or denial of service through memory corruption.
