Format string vulnerability in the _msgout function in rpc.pcnfsd in IBM AIX 6.1, 5.3, and earlier; IBM VIOS 2.1, 1.5, and earlier; NFS/ONCplus B.11.31_09 and earlier on HP HP-UX B.11.11, B.11.23, and B.11.31; and SGI IRIX 6.5 allows remote attackers to execute arbitrary code via an RPC request containing format string specifiers in an invalid directory name.

Security readout for executives and security teams

CVE-2010-1039 is a remote code execution flaw in the PC-NFS daemon used on legacy Unix platforms. A malformed RPC request can trigger unsafe format-string handling. Organizations still running exposed AIX, VIOS, HP-UX, or IRIX systems should treat this as a serious legacy infrastructure risk. Exposure is most likely in legacy Unix environments where rpc.pcnfsd or NFS/ONCplus remains installed, enabled, and reachable over network RPC. Internet exposure is not established by the bundle; internal datacenter or OT networks are more plausible. Prioritize remediation for any reachable legacy Unix host because the stated impact is arbitrary code execution. If the service is absent or tightly isolated, urgency decreases but should remain tracked due to age and support risk. Mitigation focus: Review IBM, HP, and SGI vendor guidance for supported fixes.; Apply relevant vendor APARs, patches, or replacement packages where available.; Disable rpc.pcnfsd or NFS/ONCplus if not operationally required..
