DESCRIPTION:
Andrei Costin has discovered a vulnerability in Ghostscript, which
can be exploited by malicious people to compromise a vulnerable
system.

The vulnerability is caused due to a boundary error when processing
the "OutputFile" device parameter and can be exploited to cause a
heap-based buffer overflow via an overly long filename string in a
PostScript document.

Successful exploitation may allow execution of arbitrary code.

The vulnerability is confirmed in version 9.04 running on Windows.
Other versions may also be affected.

SOLUTION:
Update to version 9.05.
