CVE-2006-4342

Name of the Vulnerable Software and Affected Versions Red Hat Enterprise Linux version 3

Description The issue allows local users to cause a denial of service, resulting in a deadlock. This occurs when the shmat function is run on a shared memory segment at the same time that the shmctl function is removing that segment, which prevents a spinlock from being unlocked.

Recommendations For Red Hat Enterprise Linux version 3, consider restricting access to the shmat and shmctl functions to minimize the risk of exploitation. As a temporary workaround, avoid running the shmat function on an shm at the same time that shmctl is removing that shm.
