DESCRIPTION:
Charlie Miller 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 an integer overflow error in
CoolType.dll when parsing the "maxCompositePoints" field value in the
"maxp" (Maximum Profile) table of a TrueType font. This can be
exploited to corrupt memory via a PDF file containing a specially
crafted TrueType font.

Successful exploitation may allow execution of arbitrary code.

The vulnerability is confirmed in Adobe Reader versions 8.2.3 and
9.3.3 and Adobe Acrobat version 9.3.3. Other versions may also be
affected.

SOLUTION:
Do not open untrusted PDF files.

PROVIDED AND/OR DISCOVERED BY:
Charlie Miller, Independent Security Evaluators.
