TITLE:
Adobe Acrobat/Reader "util.printf()" Buffer Overflow

SECUNIA ADVISORY ID:
SA29773

VERIFY ADVISORY:
http://secunia.com/advisories/29773/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
Adobe Acrobat 8.x
http://secunia.com/advisories/product/12256/
Adobe Reader 8.x
http://secunia.com/advisories/product/12829/

DESCRIPTION:
Secunia Research has discovered a vulnerability in Adobe
Reader/Acrobat, which can be exploited by malicious people to
compromise a user's system.

The vulnerability is caused due to a boundary error when parsing
format strings containing a floating point specifier in the
"util.printf()" Javascript function and can be exploited to cause a
stack-based buffer overflow via a specially crafted PDF.

Successful exploitation may allow execution of arbitrary code, but
requires that the user is e.g. tricked into opening a malicious PDF
file.

The vulnerability is confirmed in Adobe Reader version 8.1.2. Other
versions may also be affected.

SOLUTION:
The vendor will be releasing fixes later today.

NOTE: This was supposed to be a coordinated disclosure with Adobe,
but a third party has leaked the information.

PROVIDED AND/OR DISCOVERED BY:
Dyon Balding, Secunia Research.
