Description:
Mehdi Oudad and Kevin Fernandez have reported a vulnerability in ktools, which has an unknown impact.
The vulnerability is caused due to a boundary error in the "VGETSTRING()" macro when generating the output string using the "vsprintf()" function. This can be exploited to cause a stack-based buffer overflow via an overly long input string.
The vulnerability has been reported in version 0.3. Other versions may also be affected.
Note: All applications that use the Ktools library to create text-mode user interfaces are potentially affected. The actual impact depends on whether the application uses any external data sources to populate the treeview or the verticalmenu control.
Solution:
Restrict use of affected applications to only accept input from trusted sources.
Provided and/or discovered by:
Mehdi Oudad "deepfear" and Kevin Fernandez "Siegfried", Zone-H Research Team.
Changelog:
2005-12-07: Added CVE reference.
