Description Neil Horman 2005-04-18 19:19:07 UTC
+++ This bug was initially created as a clone of Bug #148862 +++

Read the description of this issue at 
http://www.gelato.unsw.edu.au/linux-ia64/0409/11073.html

A patch for 2.6 was committed:
http://lia64.bkbits.net:8080/linux-ia64-release-2.6.11/cset@41f2d1eePludGYyb1yOmGaW6Iois8Q

Impact looks like it is a unprivileged DoS at least, possibly more.

Currently embargoed, no date set.

Not needed for RHEL4. This bug only occurs if CONFIG_AUDIT=n

test case to recreate bug

This bug is re-createable with the above test case (provided by intel) on all
of our RHEL4 kernels, GA through the cvs head.
