Description Mark J. Cox 2005-10-10 11:58:33 UTC

Race condition in Linux 2.6, when threads are sharing memory mapping via
CLONE_VM (such as linuxthreads and vfork), might allow local users to cause a
denial of service (deadlock) by triggering a core dump while waiting for a
thread that has just performed an exec.

Fixed upstream in 2.6.11:
