SecurityTracker Alert ID:  1015618
SecurityTracker URL:  http://securitytracker.com/id/1015618
CVE Reference:   CVE-2006-0301   (Links to External Site)
Date:  Feb 13 2006
Impact:   Execution of arbitrary code via network, User access via network
Fix Available:  Yes  Vendor Confirmed:  Yes  

Description:   A vulnerability was reported in KDE's pdf viewer (kpdf). A remote user can cause arbitrary code to be executed on the target user's system. xpdf is also affected.

kpdf uses xpdf code that contains a heap overflow in the splash rasterizer engine. A remote user can create a specially crafted pdf file that, when viewed by the target user, will execute arbitrary code on the target user's system.

Impact:   A remote user can create a specially crafted file that, when viewed by the target user, will execute arbitrary code on the target user's system.
Solution:   Red Hat has released a fix for Xpdf, which is affected by this KDE vulnerability.
