SecurityTracker Alert ID:  1018917
SecurityTracker URL:  http://securitytracker.com/id/1018917
CVE Reference:   CVE-2007-4033, CVE-2007-5393   (Links to External Site)
Date:  Nov 8 2007
Impact:   Execution of arbitrary code via network, User access via network

Version(s): 3.02
Description:   Several vulnerabilities were reported in Xpdf. A remote user can cause arbitrary code to be executed on the target user's system.

A remote user can create a specially crafted PDF file that, when loaded by the target user, will execute arbitrary code on the target system. The code will run with the privileges of the target user.

A specially crafted Type 1 font filename can trigger a flaw in the t1lib library and cause code execution [CVE-2007-4033]

Specially crafted data can trigger a memory corruption error in the DCTStream::readProgressiveDataUnit() function in 'xpdf/Stream.cc' [CVE-2007-4352].

Specially crafted data can trigger an integer overflow in the DCTStream::reset() function in 'xpdf/Stream.cc' [CVE-2007-5392].

A specially crafted CCITTFaxDecode filter can trigger a heap overflow in the CCITTFaxStream::lookChar() function in 'xpdf/Stream.cc' [CVE-2007-5393].

The vendor was notified on October 17, 2007.

Alin Rad Pop of Secunia Research reported three of these vulnerabilities. r0ut3r discovered one of these vulnerabilities.

Impact:   A remote user can create a file that, when loaded by the target user, will execute arbitrary code on the target user's system.
Solution:   Red Hat has released a fix for CVE-2007-4033 and CVE-2007-5393.
