Technical Description:

Adobe Acrobat and Adobe Reader are vulnerable to a buffer overflow, caused by improper bounds checking of embedded JBIG2 image streams. By persuading a victim to open a specially-crafted .PDF file, a remote attacker could overflow a buffer and execute arbitrary code on the system with privileges of the victim or cause the application to crash.

Remediation:

Patches were made available on  March 10, 2009.  IBM ISS customers should also enable protection described in this alert.
