See https://lists.openafs.org/pipermail/openafs-announce/2007/000187.html It does mention a workaround, but I don't know whether upgrading or the workaround is the more desirable solution. Openafs-1.4.3_rc2 has been tested for 34 days now, without any reported problems. The list with changes from this version to 1.4.4 can be seen at http://www.openafs.org/cgi-bin/wdelta/openafs-stable-1_4_x/index/month/openafs/?only_with_tag=openafs-stable-1_4_x as everything starting from STABLE14-openafs-1-4-3fc2-20070212, up till Mar 20, 2007. Possibly STABLE14-no-default-setuid-20070319 is the only critical fix. This description is mainly a forward of information, I leave it up to you to draw conclusions. Reproducible: Didn't try Steps to Reproduce:
http://www.frsirt.com/english/advisories/2007/1033 (CVE-2007-1507) Apparently the 1.5.x branch is vulnerable as well. The bug is corrected with versions 1.4.4 and 1.5.17
Thx for the notification Stefaan. Please provide updated ebuilds.
Ebuilds for openafs-1.4.4 are already in the tree, and have been tested by myself for x86 and amd64 (though shortly, but they seem to be functioning). Another possibility of course is to backport the fix to the current stable version, but I don't know if that's worth the effort. (Personally, I'd prefer going with 1.4.4, if possible of course)
Thx Stefaan didn't notice that the fix was already committed. Arches please test and mark stable. Target keywords are: openafs-1.4.4.ebuild="alpha amd64 ia64 ppc ppc64 x86" Note rerating severity, this appears to open the possibility of a complete remote system compromise. Security please draft the GLSA request.
ppc stable

(In reply to comment #9) Could you check if config.log contains | #define HAVE_UCONTEXT_H 1 ? If so, could you try rebuilding with -DUSE_UCONTEXT?

(In reply to comment #12) > ia64 openafs-1.4.4 # CFLAGS="-O2 -pipe -DUSE_CONTEXT" emerge --oneshot openafs I'm afraid there's a spelling error in here. Could you try again with -DUSE_UCONTEXT?
Thx. Security please draft GLSA draft.
Bah, doing it right this time... sorry, Stefaan... I'll let you know.
Stefaan: new error... http://dev.gentoo.org/~wolf31o2/openafs-error.txt
(In reply to comment #16) > Stefaan: new error... http://dev.gentoo.org/~wolf31o2/openafs-error.txt > I think it gives the same error with 1.4.2, bug 156008
Thanks, Raúl... since ia64 isn't security-supported, I'll track the problem in that bug.
finally GLSA 200704-03, thanks everybody
