TITLE:
Tex Live "predospecial()" Integer Overflow Vulnerability

SECUNIA ADVISORY ID:
SA39390

VERIFY ADVISORY:
http://secunia.com/advisories/39390/

DESCRIPTION:
A vulnerability has been reported in Tex Live, which can potentially
be exploited by malicious people to compromise a user's system.

The vulnerability is caused due to an integer overflow error in the
"predospecial()" function in dospecial.c when handling .dvi files.
This can potentially be exploited to cause a heap-based buffer
overflow.

Successful exploitation may allow execution of arbitrary code if a
user is tricked into processing a specially crafted .dvi file.

SOLUTION:
Fixed in the SVN repository.
http://www.tug.org/svn/texlive/trunk/Build/source/texk/dvipsk/dospecial.c?r1=16465&r2=17559
