CVE-2010-4227: Buffer Overflow
First published: Fri Feb 25 2011(Updated: )
The xdrDecodeString function in XNFS.NLM in Novell Netware 6.5 before SP8 allows remote attackers to cause a denial of service (abend) or execute arbitrary code via a crafted, signed value in a NFS RPC request to port UDP 1234, leading to a stack-based buffer overflow.
