Adobe Acrobat Javascript for PDF Integer Overflow Vulnerability
------------------------------------------------------------------------


SUMMARY

A vulnerability allows remote attackers to execute arbitrary code on
vulnerable installations of Adobe Acrobat and Adobe Reader. User
interaction is required to exploit this vulnerability in that the target
must visit a malicious web address or open a malicious file.

DETAILS

Vulnerable Systems:
* Adobe Reader 8.1.1 and earlier versions
* Adobe Acrobat 8.1.1 and earlier versions

Immune Systems:
* Adobe Reader 8.1.2
* Adobe Acrobat 8.1.2

The specific flaw exists in the parsing of embedded JavaScript code within
PDF documents. When the function printSepsWithParams() is called with
certain malicious parameter values an integer overflow can occur resulting
in a memory corruption. This may be subsequently leveraged to execute
arbitrary code under the privileges of the current user.

Vendor Response:
Adobe has issued an update to correct this vulnerability. More details can
