Stack-based buffer overflow in the xdrDecodeString function in XNFS.NLM in Novell NetWare 6.5 SP8 allows remote attackers to execute arbitrary code or cause a denial of service (abend or NFS outage) via long packets.

Security readout for executives and security teams

CVE-2011-4191 affects the NFS component on Novell NetWare 6.5 SP8. A malformed long network packet can crash NFS or potentially let a remote attacker run code. Business exposure is mainly legacy infrastructure still serving NFS from NetWare. Likely limited to organizations still operating Novell NetWare 6.5 SP8 with XNFS.NLM/NFS enabled and reachable. Internet exposure would materially increase risk, but the provided sources do not quantify prevalence. Treat as high priority if NetWare NFS is still in production. The practical urgency depends on whether the legacy service is reachable, but remote code execution and outage potential justify fast inventory and containment. Mitigation focus: Identify any NetWare 6.5 SP8 systems running XNFS.NLM or NFS.; Review Novell bug and download references for vendor guidance or update availability.; Disable NFS/XNFS.NLM where it is not required for business operations..
