public, removing embargo http://www.isec.pl/vulnerabilities/isec-0022-pagefault.txt Created attachment 109912 [details]
upstream 2.6.10 patch
Here's what got merged upstream, we'll need to modify this somewhat though, as
exec-shield plays in the same area.
actually, that's on top of about 4-5 patches in the same area, so it's not particularly helpful without the other bits. Created attachment 109981 [details]
expand stack race fix
The patch from comment #5 is taken from the -ac patch, and should fix this issue. I haven't tested this yet, but Dave mentioned that he had a test program. I was mistaken. (Getting my isec.pl advisories mixed up) I don't have a test for this issue. An advisory 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. http://rhn.redhat.com/errata/RHSA-2005-092.html |
