What is CVE-2010-4227?

The xdrDecodeString function within the NFS component of Novell Netware 6.5 prior to Service Pack 8 is susceptible to a vulnerability that can be exploited by remote attackers.

This flaw underscores the importance of promptly applying security updates and monitoring NFS interactions.
