Adobe Reader: User-assisted execution of arbitrary code

Background

Adobe Reader (formerly Adobe Acrobat Reader) is a closed-source PDF reader.

Description

The Johns Hopkins University Applied Physics Laboratory reported that input to an unspecified JavaScript method is not properly validated.

Impact

A remote attacker could entice a user to open a specially crafted PDF document, possibly resulting in the remote execution of arbitrary code with the privileges of the user.

Workaround

There is no known workaround at this time.

Resolution

All Adobe Reader users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=app-text/acroread-8.1.2-r3"
