Description solar (RETIRED) gentoo-dev 2004-09-15 10:17:12 UTC
The X.Org Foundation is pleased to announce X11R6.8.1, the latest
stable release of X.Org, the X standard implementation.

This version is purely a security release, addressing multiple integer
and stack overflows in libXpm, the X Pixmap library; all known versions
of X (both XFree86 and X.Org) are affected, so all users of X are
strongly encouraged to upgrade.  Vendors should have patches available
for their versions of X.

The CVE numbers for these vulnerabilities are CAN-2004-0687 (integer
overflows) and CAN-2004-0688 (stack overflows).

For the 6.8.1 release, two choices have been provided -- the standard
set of seven tarballs, and a single tarball.

If you download the traditional split tarballs, the first three contain
everything except the fonts and general X11 documentation.  Those three
are sufficient for building X11R6.8 if you already have a set of fonts.
The fourth and fifth contain the fonts.  The sixth contains the source
for the general X11 documentation.  The seventh contains the general
X11 documentation in hardcopy format.

For the single tarball (xorg-6.8.0.tar.gz), everything described in the
previous paragraph is available in the single tarball.

Comment 1 Donnie Berkholz (RETIRED) gentoo-dev 2004-09-15 12:20:26 UTC
I'm running a test compile of the patched 6.7.0 right now, 6.8.1 coming up soon.
Comment 2 Donnie Berkholz (RETIRED) gentoo-dev 2004-09-15 13:51:57 UTC
Seems like a little confusion going on w/ the security release. See -- it announces that a release will be made tomorrow, but the previous posts say there was already one.
Comment 3 Donnie Berkholz (RETIRED) gentoo-dev 2004-09-15 23:00:30 UTC
I'm holding off till tomorrow to see whether more changes are made.
Comment 4 Thierry Carrez (RETIRED) gentoo-dev 2004-09-16 01:12:53 UTC
I suppose old xfree is vulnerable... Do you plan to issue fixed packages for xfree too ? If not, then we'll security-mask xfree, which will probably help getting rid of it. But I don't know if we're ready for this on all arches etc.. You have the cards in hand, you decide and we'll follow.
Comment 5 Donnie Berkholz (RETIRED) gentoo-dev 2004-09-16 19:05:40 UTC
I suppose that's a good idea, given my previous statement of support til 2005.0. I'll be pulling the heavily modified xfree then (currently -r7) and replacing it with a security-fixed -r6. If anyone needs the current -r7 (possibly hardened people?), this is a good time to speak up.

Comment 7 Donnie Berkholz (RETIRED) gentoo-dev 2004-09-16 23:00:49 UTC
xorg-x11-6.7.0-r2 is fixed. It needs to reach:

"x86 sparc alpha arm hppa mips ppc64 ppc amd64 ia64"

xorg-x11-6.8.0-r1 is fixed. It needs to reach:

"~x86 ~amd64 ~ppc ~mips"

A fix is forthcoming for xfree.

ppc64 is a little out of luck on xorg-6.7.0-r2 because it jumped ahead of the maintainer's arch and stabled. It can opt to tell users to re-merge 6.7.0-r2 or mark 6.8.0-r1 stable.
Comment 8 Donnie Berkholz (RETIRED) gentoo-dev 2004-09-16 23:04:51 UTC
Apologies, 6.8.0-r1 also needs:

ppc64 ~ia64 ~hppa (from 6.7.99.x ebuilds)
Comment 9 Donnie Berkholz (RETIRED) gentoo-dev 2004-09-16 23:33:11 UTC
xfree-4.3.0-r7 is now a security release. It needs to reach:

x86 ppc sparc alpha mips hppa amd64 ia64 (based on -r5 and -r6)

Any arches that don't reach stable xfree will no longer have any xfree in portage, because everything else will be pulled.
Comment 10 Donnie Berkholz (RETIRED) gentoo-dev 2004-09-16 23:34:04 UTC
I've started the ebuilds as ~x86. Could another x86 tester please confirm and mark them stable please?
Comment 11 Donnie Berkholz (RETIRED) gentoo-dev 2004-09-16 23:34:41 UTC
(Note: The above comment doesn't apply to xorg 6.8)
Comment 12 Sune Kloppenborg Jeppesen gentoo-dev 2004-09-16 23:52:08 UTC
Arches please test and mark stable:



xfree-4.3.0-r7 (x86 please test and mark stable)

Exact keywords provided by Donnie above.
Comment 13 Jochen Maes (RETIRED) gentoo-dev 2004-09-17 01:41:50 UTC
marked stable on ppc
not marked stable on ppc, Xorg doesn't start up descently (greenish-white screen)
tried install 2 (each time i went back to 6.7.0, and did not change config)
won't mark stable untill fixed.
Comment 14 Thierry Carrez (RETIRED) gentoo-dev 2004-09-17 03:04:01 UTC
Jochen : you don't need to mark stable xorg-x11-6.8*. To clarify what keywords are needed on security POV :

x86, sparc, alpha, arm, hppa, ia64 :
stable : (xorg-x11-6.7.0-r2 or xorg-x11-6.8.0-r1) and xfree-4.3.0-r7

ppc :
stable : xfree-4.3.0-r7
~ : xorg-x11-6.8.0-r1

mips,amd64 :
stable : (xorg-x11-6.7.0-r2 or xorg-x11-6.8.0-r1) and xfree-4.3.0-r7
~ : xorg-x11-6.8.0-r1

ppc64 :
all set, though they could try to mark xorg-x11-6.8.0-r1 stable to cover for people with package.unmasked xorgs.

When x86,sparc,ppc and amd64 wil have the required stable keywords, the GLSA will go out. Arches not stable-izing xfree-4.3.0-r7 will in effect deprecate xfree on their arches since the GLSA will instruct xfree users to migrate and all old xfree versions will be package-masked or retired.
Comment 15 Jochen Maes (RETIRED) gentoo-dev 2004-09-17 04:22:31 UTC
marked xorg-x11-6.8.0-r1.ebuild unstable
as discussed in PPC meetings we won't support XFree anymore on ppc.
Comment 16 Ferris McCormick (RETIRED) gentoo-dev 2004-09-17 04:52:57 UTC
sparc needs sparc-specific patches applied for both xfree & xorg-6.8.0-r1 (patches provided for both),
and xfree is deprecated in favor of xorg because of libGL problems.
I'll verify for sparc later, but right now, as far as I know,
1. xfree-4.3.0 will not run anything requiring libGL (without patches to libGL & Mesa);
2. xorg-6.8.0 will not run on any 2.4.xx kernel if the user has sparc keyboard,
   nor will it build at all on some sparc32 systems without some ebuild patching (or equivalent).
So xfree is not stable, and the most xorg-6.8.0-<anything> could get from sparc is a ~sparc, until I get feedback from other sparc people to the contrary.
Comment 17 Thierry Carrez (RETIRED) gentoo-dev 2004-09-17 05:48:14 UTC
ppc is done.

Ferris : if you can mark xorg-x11-6.7.0-r2 stable on sparc and xfree support is deprecated, that's all we need as far as security is concerned.
Comment 18 Ian Leitch (RETIRED) gentoo-dev 2004-09-17 05:58:19 UTC
The following bugs needs to be addressed before 6.8.0-r1 can go stable on x86, and possibly other arches. 

#63548 #63567 #63647 #63732 #63759 #63795 #63924 #63890 #64129 #64377

There may be more, I only did a quick scim.
Comment 19 Ferris McCormick (RETIRED) gentoo-dev 2004-09-17 07:04:30 UTC
I'm building xorg-x11-6.7.0-r2 now to make sure it actually builds.  Then I'll mark it ~sparc
for a couple days, then go stable.  (We were hoping to go from ...-r1 to 6.8.0
because once 6.8 gets built, it is a better choice for sparc (performance issues).
But it won't build successfully for all systems without some ebuild help.  That's what
Bug 63994 is about, mostly.  I suppose I should have added it to the blocker list.)

Anyway, #63994 should be part of Comment 18's list, as a summary of all sparc issues.
Comment 20 Donnie Berkholz (RETIRED) gentoo-dev 2004-09-17 09:25:52 UTC
we're not stabling 6.8.0 on x86. We're ~arch'ing it. I thought I made that clear above.

The only arch I would suggest stables 6.8 is ppc64, because that's the only way they can get an automatic upgrade to a "safe" ebuild.
Comment 21 Travis Tilley (RETIRED) gentoo-dev 2004-09-17 10:55:54 UTC
i have no problems with xfree being dropped for amd64. we dont support it anymore anyways... at all. actually, i think i should ~amd64 all current xfree ebuilds just to make sure that point gets across.

xorg 6.7.0-r2 stable on amd64
Comment 22 Ferris McCormick (RETIRED) gentoo-dev 2004-09-17 13:14:29 UTC
6.7.0-r2 has ~sparc keyword now.  Testing and feedback required before it can go
stable.  We (sparc) prefer 6.8.0-r1, awaiting some ebuild changes to permit clean
build, install, and actual use. (Comments 16, 19 above).
Comment 23 Stephen Becker (RETIRED) gentoo-dev 2004-09-17 22:30:50 UTC
Marked 6.7.0-r2 and 6.8.0-r1 ebuilds stable and testing on mips, respectively.  As for xfree, it is deprecated.  Xorg-x11 is the default in our profile, so I say let xfree die.
Comment 24 Bryan Østergaard (RETIRED) gentoo-dev 2004-09-18 03:45:45 UTC
Alpha done.
Comment 25 Thierry Carrez (RETIRED) gentoo-dev 2004-09-18 09:30:28 UTC
Update on stable need :

Arches still needing xorg-x11-6.7.0-r2 stable (or 6.8.0-r1 if you prefer this version) :
x86, sparc, ia64

Arches still needing to mark stable xfree-4.3.0-r7 or officially decide it is deprecated :
x86, sparc, hppa, ia64

Arches that have already declared xfree deprecated :
ppc, amd64, mips
Comment 26 Guy Martin (RETIRED) gentoo-dev 2004-09-18 09:37:27 UTC
xorg-x11 is already the default on hppa and xfree is considered deprecated.

Does anything needs to be done into the cvs to deprecated xfree besides changing the default virtual ?
Comment 27 Ferris McCormick (RETIRED) gentoo-dev 2004-09-18 12:33:51 UTC
Also for sparc, xorg-x11 is the default and xfree is deprecated.

Otherwise, comments regarding xorg are unchanged: 6.8.0-r1 is awaiting ebuild changes and 6.7.0-r2 is ~sparc for testing.
(Comments 19, 22, etc.)
Comment 28 Ferris McCormick (RETIRED) gentoo-dev 2004-09-20 05:06:33 UTC
Our daily update summary for sparc:
1. xfree is no longer supported (hasn't been, really, since late May).

2. xorg-x11-6.7.0-r2 is ~sparc for testing; guaranteed to FAIL on hardened
   systems (xorg issues, not toolchain).
   Marking this stable would have the curious meaning "stable for sparc unless  for you it isn't".

3. xorg-x11-6.8.0-r1 seems fine so far, but cannot get any sort of sparc keyword    withoug ebuild help (documented reasons all over the place).
   I can commit the ebuild changes, x11 herd can commit them, but until they are
   there, 6.8.0-r1 seems to be in the state "this is the best fix, and you (sparc    people) should plan to use it, except if you build it, it probably won't work
   for you unless you fix the ebuild by hand first".

Sorry to keep beating this, but I hope you see our difficulty.
Comment 29 Thierry Carrez (RETIRED) gentoo-dev 2004-09-20 05:32:34 UTC
Ferris, about your point 2 above :

xorg-x11-6.7.0-r1 is marked stable on sparc. I suppose it has the same xorg/hardened issues as xorg-x11-6.7.0-r2 ? If this is really the case, then it should be marked stable anyway.

Security stable marks follow this rule : if it doesn't work worse than the previous stable one, it should be marked stable even if there are unfixed known bugs. So, unless those xorg/hardened problems are new to 6.7.0-r2, this version should be marked stable.
Comment 30 Ferris McCormick (RETIRED) gentoo-dev 2004-09-20 06:52:32 UTC
Koon, problem comes in because the option to harden gcc came after xorg-x11-6.7.0-r1.
Anyone who chose to harden will be asked to upgrade from a working xorg to a for-sure
not working one unless we provide the 6.8.0-r1 option.

A new installation would run into the problem this way only:
1. Install;
2. Rebuild hardened;
3. Build xorg-x11

An existing (running hardened system) runs into the problem this way:
1. Upgrade xorg-x11
Since 6.8.0-r1 does not have the problem, we MUCH prefer that alternative.  We
don't know if this is much of a problem in practice, but would prefer not to find out.
Comment 31 Ferris McCormick (RETIRED) gentoo-dev 2004-09-20 06:58:39 UTC
Let me add a line:  6.7.0-r2 just got ~sparc, and we need minimal cofirmation it
runs OK unhardened.  It can go stable much faster if the 6.8.0-r1 can go ~sparc as well.
Comment 32 Donnie Berkholz (RETIRED) gentoo-dev 2004-09-20 08:56:20 UTC
I'll try to get your 6.8 changes in ASAP, Ferris, but I've been quite busy the past few days. Maybe tonight I can.
Comment 33 Ferris McCormick (RETIRED) gentoo-dev 2004-09-20 11:53:46 UTC
Thanks a lot.  I just applied the patch on Bug 63994 to current xorg-x11-6.8.0-r1.ebuild as test.
One piece is now off by 3 lines, otherwise it applied cleanly.  I used it to build
on a hardened kernel-2.4.27 system.  Build, install went with no problems, and
that system is now happily running 6.8.0-r1

For sparc, xorg-x11-6.8.0-r1 now is also ~sparc for testing.  We'll decide shortly
which version (6.7.0-r2, 6.8.0-r1) we want to be considered stable and mark it so.
(I personally favor 6.8.0-r1, but we still await user feedback.)
Comment 35 Thierry Carrez (RETIRED) gentoo-dev 2004-09-22 08:35:43 UTC
Ferris: waiting for your decision.
Someone (x86 team ? X maintainers ?) should also mark stable both xfree-4.3.0-r7 and xorg-x11-6.7.0-r2 for x86.
Comment 36 Donnie Berkholz (RETIRED) gentoo-dev 2004-09-22 09:13:07 UTC
I guess I can assume it's been tested at this point. Stabled on x86.
Comment 37 Donnie Berkholz (RETIRED) gentoo-dev 2004-09-22 09:14:57 UTC
Just a little note:

ALWAYS make a ChangeLog entry for things in x11-base. I don't care whether it's keywording or whatever.
Comment 38 Ferris McCormick (RETIRED) gentoo-dev 2004-09-22 10:54:48 UTC
Koon, re sparc:  It's 99.44% certain to be 6.8.0-r1 stable.  Please bear with us
for a couple more days, because:
(1) Thanks to support from xorg (ajax) and x11 herd (spyderous), we now seem to
    have a clean xorg-x11-6.8.0-r1.ebuild.  So, we would like to avoid 6.7.0-r2 if possible (no one is using it).
(2) Because of hardware limitations, one or two tests have to wait a couple days
    (where "couple" means "not more than 3").
(3) Because the build cycle takes so long on sparc, we need to give anyone inclined
    to test a day at least to build & verify, once it becomes possible.

Later today I will distribute a notice to the world to the effect that "If you've
got something against xorg-x11-6.8.0-r1, your chance to make your objections count
will end by some time this weekend."
Comment 39 Thierry Carrez (RETIRED) gentoo-dev 2004-09-22 13:35:59 UTC
Ferris: we're already two days late in our GLSA release (target delay for this kind of vulnerability is 5 days), so the sooner the better.
