CVE-2013-3266: Freebsd

High severity, CVSS 7.5. EPSS: 3.5% chance of exploitation in the next 30 days.

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.

Affected products

• Freebsd Freebsd: version 8.0 only; version 8.1 only; version 8.2 only; version 8.3 only; version 9.0 only; version 9.1 only
