hardened-sources: Please stablize 2.6.17-r1 or higher. xen-Sources: Bump to 2.6.17 or patch. vserver-sources: Bump to 2.6.17 or patch. rsbac-sources: Bump to 2.6.17 or patch. suspend2-sources: Please stablize 2.6.17-r1 or higher. systrace-sources: Bump to 2.6.17 or patch.
i have removed all vserver-sources < 2.6.17
FYI xen-sources will be bumped to 2.6.18 in the very near future to address this and other security issues. Hopefully, we can also use genpatches to make things easier in the future.
All done except xen and systrace
systrace-sources and xen-sources will be put into package.mask as of the 12/19/2006. Please bump to ~arch, or contact me to pospone the hardmasking.
xen-sources-2.6.16.28 has been in the tree since 10 Sep 2006 and is not vulnerable (as per http://lwn.net/Articles/197177/). I'll remove 2.6.16.26 when cvs.g.o is available again.
All vulnerable version of xen-sources (<2.6.16.28) have been removed.
package.mask on the 27th.
systrace-sources is now in package.mask
