Description
Adobe Reader and Acrobat contain a vulnerability that could allow an unauthenticated, remote attacker to cause a denial of service condition or execute arbitrary code on a targeted system.

The vulnerability is due to an unspecified flaw the in the affected software. An unauthenticated, remote attacker could exploit the vulnerability by persuading a user to open a crafted .pdf file. When the .pdf is processed by the affected software, malicious JavaScript could compile and execute arbitrary code or cause the affected software to terminate abnormally. A successful exploit could allow the attacker to cause a DoS condition or execute arbitrary code in the security context of the user running the affected application. If the user holds elevated privileges, the attacker could cause a complete system compromise.

Adobe has confirmed the vulnerability and software updates are available.
 
Warning Indicators
Adobe Reader and Acrobat versions 11.0.01 and prior, 10.1.5 and prior, 9.5.3 and prior are vulnerable.
