Description Mark J. Cox (Product Security) 2007-10-10 08:48:37 EDT
Using asynchronous IO on a FIFO causes RHEL 3U9 to kernel panic.

(Does not occur in RHEL 4 as the pipe_write function has been re-written) 

This is a security issue because a local unprivileged user can cause a kernel panic.

Reproducer in bz#311621

This issue posted on 2008-06-05 to upstream security list. Reviewed and
confirmed by Don Howard and Josef Bacik, this issue not present in upstream
vanilla 2.4.21 kernel -> lifting the embargo for this one.
