Description Flags
Patch for e1000 kernel mem leak none

Description Mark J. Cox 2004-06-03 12:28:04 UTC 
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)

Note that a number of security databases have incorrect information
regarding this issue.  Originally, ISS said this was a privilege
escalation vulnerability: http://xforce.iss.net/xforce/xfdb/16159 
They have since updated this page to explain that it is an information
leak, but there are still remnants of the old content viewable (the
page still erroneously lists the vulnerability as "high priority" and
with "gain privileges" consequences)

Comment 3 Ernie Petrides 2004-06-15 10:03:53 UTC 
A fix for this problem has just been committed to the RHEL3 U3
patch pool this evening (in kernel version 2.4.21-15.11.EL)
with the upgrade of the e1000 driver to version 5.2.52-k1
(which doesn't contain the mem leak addressed by comment #1).
Comment 4 Ernie Petrides 2004-07-31 06:00:08 UTC 
A fix for this problem has also been committed to the RHEL3 E3
patch pool (in kernel version 2.4.21-15.0.4.EL).
