Vulnerability Description
A heap corruption vulnerability has been reported in Adobe Reader and Acrobat. Adobe Reader and Acrobat is a family of computer programs developed by Adobe Systems, designed to view, create, manipulate and manage files in Adobe's core technology, the Portable Document Format (PDF), a format that has become the de facto standard in the electronic document exchange. Successful exploitation of this vulnerability may allow execution of arbitrary code on a target system.
Vulnerability Status

Successful exploitation will create a denial of service condition, causing the application to become non-responsive, and may allow execution of arbitrary code once a malicious PDF file is loaded on a vulnerable system.
