The kernel key management code did not correctly handle key reuse. A local attacker could create many key requests, leading to a denial of service. (CVE-2007-0006)
The kernel NFS code did not correctly validate NFSACL2 ACCESS requests. If a system was serving NFS mounts, a remote attacker could send a specially crafted packet, leading to a denial of service. (CVE-2007-0772)
