TITLE:
Ghostscript jbig2dec JBIG2 Processing Buffer Overflow Vulnerability

SECUNIA ADVISORY ID:
SA34292

VERIFY ADVISORY:
http://secunia.com/advisories/34292/

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

The vulnerability is caused due to a boundary error in the included
jbig2dec library while decoding JBIG2 symbol dictionary segments.
This can be exploited to cause a heap-based buffer overflow via a
specially crafted PDF file.

Successful exploitation may allow execution of arbitrary code.

The vulnerability is confirmed in version 8.64. Other versions may
also be affected.

SOLUTION:
Do not process untrusted PDF files.
