Novell BorderManager Client Trust Buffer Overflow Vulnerability

Secunia.com 2007-11-01 , release at their website a vulnerability has been reported in Novell BorderManager, which can be exploited by malicious people to compromise a vulnerable system.
The vulnerability is caused due to the Client Trust application incorrectly processing validation requests sent to the UDP port on which clntrust.exe is listening (by default 3024). This can be exploited to cause a heap-based buffer overflow by sending a specially crafted validation request containing a Novell tree name without backslash or zero wide characters.

Successful exploitation allows execution of arbitrary code.

The vulnerability is reported in Novell BorderManager 3.8. Prior versions may also be affected.

Solution : Download patch from Vendor
