The nfsrvd_readdir function in sys/fs/nfsserver/nfs_nfsdport.c in the new NFS server in FreeBSD 8.0 through 9.1-RELEASE-p3 does not verify that a READDIR request is for a directory node, which allows remote attackers to cause a denial of service (memory corruption) or possibly execute arbitrary code by specifying a plain file instead of a directory.

Security readout for executives and security teams

This flaw affects the FreeBSD new NFS server in older 8.x and 9.1-era releases. A remote attacker could send an unexpected directory-read request against a normal file, potentially crashing the server and possibly causing code execution. Business risk is highest where legacy FreeBSD NFS services remain reachable. Exposure is likely limited to legacy FreeBSD systems running the new NFS server with NFS reachable by untrusted or broad internal networks. Systems not running NFS, not using affected FreeBSD versions, or already updated per vendor guidance are less likely exposed. Prioritize remediation for any reachable legacy FreeBSD NFS server. The issue is old, but remote memory corruption on a file service is operationally serious, especially if the service is exposed beyond tightly trusted networks. Mitigation focus: Apply FreeBSD fixes or updates referenced by FreeBSD-SA-13:05.; Apply Debian updates referenced by DSA-2672 where applicable.; Restrict NFS access to trusted networks and hosts only..
