Protection Provided by:	Security Gateway R81, R80, R77, R75
Who is Vulnerable?
Vulnerability Description	Adobe develops products for creating, distributing, and viewing Portable Document Format (PDF) documents. Adobe Reader is a viewer application that allows for reading and the printing of PDF documents. Adobe Acrobat provides PDF authoring functionality in addition to those of viewing. A buffer overflow vulnerability exists in Adobe Reader and Acrobat. The vulnerability is due to insufficient input validation in the getIcon() method of a Collab object, while processing a crafted PDF file. A remote attacker can exploit this vulnerability by enticing the target user to open malicious PDF files. In an attack case where code injection is not successful, the affected Acrobat application parsing the malicious PDF document can terminate abnormally. In a more sophisticated attack where code injection is successful, the behaviour of the target host is entirely dependent on the intended function of the injected code. The injected code, in this case, would execute within the security context of the currently logged in user.
