teTeX Integer Overflows in Converting DVI Files to PostScript Lets Remote Users Execute Arbitrary Code
SecurityTracker Alert ID:  1023948
SecurityTracker URL:  http://securitytracker.com/id/1023948
CVE Reference:   CVE-2010-0739, CVE-2010-1440   (Links to External Site)
Date:  May 7 2010
Impact:   Execution of arbitrary code via network, User access via network


Description:   Two vulnerabilities were reported in teTeX. A remote user can cause arbitrary code to be executed on the target user's system.

A remote user can create a specially crafted DVI file that, when converted into PostScript, will trigger an integer overflow and potentially execute arbitrary code on the target system. The code will run with the privileges of the target or application.

Impact:   A remote user can create a file that, when processed by the target application, will execute arbitrary code on the target user's system.
Solution:   No solution was available at the time of this entry.

[Editor's note: teTeX is no longer maintained by the upstream vendor. Individual Linux distributions may have fixes available.]
