Description Robert Buchholz (RETIRED) gentoo-dev 2008-04-08 15:26:09 UTC
integer overflow -> heap-based buffer overflow on rsync 3.0  and later, only when xattr is enabled.

This issue is currently under embargo until rsync upstream announces the fix.
Comment 1 Robert Buchholz (RETIRED) gentoo-dev 2008-04-08 16:21:23 UTC
Tomas Hoger:
Seems that the code that is fixed by your patch is included in
rsync-2.6.9/patches/acls.diff, so it seems it may be used by 2.6.9 as
Comment 2 SpanKY gentoo-dev 2008-04-08 17:29:13 UTC
rsync-3.0.2 was released with the fix and in the tree
Comment 3 Robert Buchholz (RETIRED) gentoo-dev 2008-04-08 18:40:10 UTC
Vapier, thanks for noting this.

2.6.9 also needs to be fixed because it applies the xattr patches. Or should 3.0.2 go through straight stabling?
Comment 4 SpanKY gentoo-dev 2008-04-10 03:38:47 UTC
while i dont have a problem with rsync-3.0.2 going stable, it may be a little too soon for the rsync-3 series

rsync-2.6.9-r6 in the tree with the upstream fix
Comment 5 Robert Buchholz (RETIRED) gentoo-dev 2008-04-10 09:05:07 UTC
Arches, please test and mark stable:

Comment 7 Tobias Scherbaum (RETIRED) gentoo-dev 2008-04-10 17:37:05 UTC
ppc stable
Comment 8 Raúl Porcel (RETIRED) gentoo-dev 2008-04-10 18:19:41 UTC
alpha/ia64/sparc stable, and compiles fine on x86
Comment 9 Markus Rothe (RETIRED) gentoo-dev 2008-04-10 18:35:05 UTC
ppc64 stable
Comment 10 Markus Meier gentoo-dev 2008-04-10 18:48:53 UTC
I can reproduce the failure on x86, if the acl USE-flag is set.
Comment 11 Markus Meier gentoo-dev 2008-04-10 19:18:38 UTC
amd64 stable (no acl-related problems here)
Comment 12 Jeroen Roovers (RETIRED) gentoo-dev 2008-04-10 19:48:41 UTC
Stable for HPPA.
Comment 13 Pierre-Yves Rofes (RETIRED) gentoo-dev 2008-04-10 20:40:11 UTC
base-system, please advise wrt comments #6 and #10.

btw, updating severity to major, dunno why it was on trivial.
Comment 14 Dawid Węgliński (RETIRED) gentoo-dev 2008-04-10 21:45:12 UTC
Yup, works here if USE="-acl".
Comment 15 SpanKY gentoo-dev 2008-04-12 20:30:04 UTC
odd that it builds for so many of us

should be fixed in cvs now
Comment 16 Dawid Węgliński (RETIRED) gentoo-dev 2008-04-12 22:34:51 UTC
x86 stable
Comment 17 Robert Buchholz (RETIRED) gentoo-dev 2008-04-17 12:02:29 UTC
A2->A1 since this affects the server too.
Comment 18 Robert Buchholz (RETIRED) gentoo-dev 2008-04-17 12:14:34 UTC
GLSA 200804-16
Comment 19 Peter Volkov (RETIRED) gentoo-dev 2008-04-21 08:01:04 UTC
Fixed in release snapshot.
