4) Description of Vulnerability
Secunia Research has discovered a vulnerability in Adobe
Acrobat/Reader, 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 when
viewing a malicious PDF file.

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.
