The vulnerability is caused due to the mount and umount programs incorrectly checking the return values of the "setuid()" and "setgid()" functions when dropping privileges. This can potentially be exploited to perform certain actions with escalated privileges via e.g. the mount.nfs utility. The vulnerability is reported in version 2.12r. Other versions may also be affected. Solution: Fixed in the util-linux-ng repository. http://git.kernel.org/?p=utils/util-linux-ng/util-linux-ng.git;a=commit;h=ebbeb2c7ac1b00b6083905957837a271e80b187e keytoaster@gentoo.org 2007-10-10 16:24:46 0000 You already applied the patch in -r8 a few days ago, but I couldn't find an appropriate security bug for this issue. Do you have plans to stabilise util-linux-2.12r-r8? Our latest stable version is vulnerable. vapier@gentoo.org 2007-10-10 18:04:43 0000 i dont have any plans for anything whatever security team wants to push is up to them, 2.12r-r8 is fine py@gentoo.org 2007-10-10 20:06:12 0000 Arches pleases test and mark stable sys-apps/util-linux-2.12r-r8 target "alpha amd64 arm hppa ia64 m68k mips ppc ppc64 s390 sh sparc x86" fauli@gentoo.org 2007-10-10 23:06:28 0000 x86 stable jer@gentoo.org 2007-10-11 03:12:28 0000 Stable for HPPA beandog@gentoo.org 2007-10-11 03:25:11 0000 amd64 stable jer@gentoo.org 2007-10-11 03:30:40 0000 Stable for SPARC. tgall@gentoo.org 2007-10-11 05:15:26 0000 stable on ppc64 armin76@gentoo.org 2007-10-11 16:21:36 0000 alpha/ia64 stable dertobi123@gentoo.org 2007-10-12 15:14:10 0000 ppc stable, ready for glsa rbu@gentoo.org 2007-10-12 17:17:28 0000 (In reply to comment #10) > ppc stable, ready for glsa request filed. py@gentoo.org 2007-10-18 21:53:42 0000 GLSA 200710-18 kumba@gentoo.org 2007-11-19 07:20:45 0000 mips stable.
