Red Hat Product Errata RHSA-2005:514 0 qe-ready SHIPPED_LIVE Important: Updated kernel packages available for Red Hat Enterprise Linux 4 Update 2 2005-10-05 04:00:00 UTC

Description Mark J. Cox 2005-06-09 09:35:00 UTC 
The following upstream patch fixes canonical checking for segment registers in
ptrace.  This allowed user programs to set a non canonical segment which would
cause oopses in the kernel later.
