-\\Discussion
Adobe Acrobat and Reader are prone to a remote code-execution vulnerability.
An attacker can exploit this issue to execute arbitrary code with the privileges of the user running the application or crash the application, denying service to legitimate users.
The issue affects Reader and Acrobat 9, 8.1.3 and prior, and 7.
UPDATE (Feb 24, 2009): Further reports suggest this issue affects the vulnerable applications running on Apple Mac OS X and various Linux based operating systems.
