Summary
A buffer overflow in Adobe Reader (and Acrobat) versions 9.x, 10.x and 11.x, prior to the fixed releases, lets the flaw be triggered when a crafted PDF is processed. An attacker who can get a malicious PDF to a user can execute arbitrary code, provided the user opens the document, so user interaction is required and no authentication or network position is needed beyond delivering the file.
Official description · NVD
Buffer overflow in Adobe Reader and Acrobat 9.x before 9.5.4, 10.x before 10.1.6, and 11.x before 11.0.02 allows remote attackers to execute arbitrary code via a crafted PDF document, as exploited in the wild in February 2013.
