Description Mark J. Cox (Product Security) 2004-06-03 08:40:26 EDT
According to
http://www.kernel.org/pub/linux/kernel/v2.4/testing/patch-2.4.27.log a
recent kernel fix was applied "e1000: fix probable security hole".

This issue in fact is a minor information leak via the e1000 driver
that can reveal 24 bytes of kernel memory to users (if e1000 driver is
loaded)

RHEL 2.1 is possibly vulnerable to this issue via the backported
driver added

No CVE name yet available
See Bug #125168 for a patch (will need to be backported)

This is covered by e1000 update in RHEL2.1 U5...
