The KEYCTL_JOIN_SESSION_KEYRING operation in the Linux kernel before
2.6.12.5 contains an error path that does not properly release the session
management semaphore, which allows local users or remote attackers to cause
a denial of service (semaphore hang) via a new session keyring (1) with an
empty name string, (2) with a long name string, (3) with the key quota
reached, or (4) ENOMEM.
