(Debian Issues Fix) Xpdf Buffer Overflow in makeFileKey2() Lets Remote Users Execute Arbitrary Code
SecurityTracker Alert ID:  1012946
SecurityTracker URL:  http://securitytracker.com/id/1012946
CVE Reference:   CVE-2005-0064   (Links to External Site)
Date:  Jan 19 2005
Impact:   Execution of arbitrary code via network, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  
Version(s): prior to 3.00pl3
Description:   iDEFENSE reported a buffer overflow vulnerability in Xpdf. A remote user may be able to execute arbitrary code on the target system.

A remote user can create a specially crafted PDF file to trigger a stack overflow in the 'Decrypt::makeFileKey2' function in the processing of the /Encrypt /Length tag. Arbitrary code can be executed with the privileges of the Xpdf process or the user running Xpdf.

The flaw resides in 'xpdf/Decrypt.cc'.

The vendor was notified on January 6, 2005.

The original advisory is available at:

http://www.idefense.com/application/poi/display?id=186&type=vulnerabilities

Impact:   A remote user can create a PDF file that, when processed by Xpdf, will execute arbitrary code on the target system. The code will run with the privileges of Xpdf.
Solution:   Debian has released a fix for the stable distribution (woody) in version 1.00-3.4 and for the unstable distribution (sid) in version 3.00-12.

Debian GNU/Linux 3.0 alias woody:
