CAN-2004-0415 file offset pointer signedness issues

Embargoed until Jun29 1600 MEST
isec.pl reported on May24 file offset pointer vulnerabilities allowing
read of kernel memory. They noted "dozens of places" with vulnerable
code and gave poc based on MTRR race.
Hi, Al. This issue is embargoed until June 29th, but we'd like to
have a RHEL3 E3-stream security errata developed in the meantime
(which will be released before U3 is released).
Due to the complexity of the issue and fixes the embargo has been
moved, currently set at Aug 3rd at 1700 UTC
A fix for this problem has just been committed to the RHEL3 E3
patch pool (in kernel version 2.4.21-15.0.4.EL).
Errata in QA; removing embargo
An errata has been issued which should help the problem
described in this bug report. This report is therefore being
closed with a resolution of ERRATA. For more information
on the solution and/or where to find the updated files,
please follow the link below. You may reopen this bug report
if the solution does not work for you.
These fixes have also been propagated to the RHEL3 U3 patch pool with
tonight's commits for the U3 respin (in kernel version 2.4.21-19.EL).
