NGSSoftware Insight Security Research Advisory Name: WildTangent Web Driver Long FileName Stack Overflow Systems Affected: WildTangent Web Driver 4.0 (earlier versions not tested) Severity: High Vendor URL: http://www.wildtangent.com Author: Peter Winter-Smith [ peter@xxxxxxxxxxxxxxx ] Date Vendor Notified: 31th March 2004 Date of Public Advisory: 27th May 2004 Advisory number: #NISR27052004 Advisory URL: http://www.ngssoftware.com/advisories/wildtangent.txt Description *********** WildTangent provide high quality interactive media technology to the Internet in the form of their WebDriver. This is used by some of the largest companies and corporations world-wide to provide advanced media content to over 80 million users of their Internet plug-in. Details ******* It is possible to cause a number of buffer overruns within the WildTangent package, namely within the WTHoster and WebDriver modules, via any method which takes a filename as an parameter. During the process of constructing an absolute path for this file, a concatenation of a predefined directory path and the filename supplied as a parameter occurs through an unchecked call to strcat(). This can easily be made to overflow the buffer and can allow arbitrary remote code execution on the target system. A working exploit has been created and tested against a vulnerable system, and as such it is highly recommended that users of the WildTangent plug-in install the updated version immediately. Fix Information *************** WebDriver 4.1 has been released to protect against the vulnerability.
