TITLE:
Ghostscript "pdf_base_font_alloc()" Buffer Overflow

SECUNIA ADVISORY ID:
SA34534

VERIFY ADVISORY:
http://secunia.com/advisories/34534/

DESCRIPTION:
A vulnerability has been reported 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
"pdf_base_font_alloc()" function in src/gdevpdtb.c. This can be
exploited to cause a stack-based buffer overflow by tricking a user
into converting a specially crafted Postscript file to PDF.

Successful exploitation may allow execution of arbitrary code.

SOLUTION:
Update to version 8.64.

PROVIDED AND/OR DISCOVERED BY:
Reported by Wolfgang Hamann in a Ghostscript bug report.
