Mandriva Linux Security Advisory 2012-083 - Multiple vulnerabilities have been discovered and corrected in util-linux. mount in util-linux 2.19 and earlier attempts to append to the /etc/mtab.tmp file without first checking whether resource limits would interfere, which allows local users to trigger corruption of the /etc/mtab file via a process with a small RLIMIT_FSIZE value, a related issue to CVE-2011-1089. mount in util-linux 2.19 and earlier does not remove the /etc/mtab~ lock file after a failed attempt to add a mount entry, which has unspecified impact and local attack vectors. The updated packages have been patched to correct this issue.

Red Hat Security Advisory 2012-0307-03 - The util-linux package contains a large variety of low-level system utilities that are necessary for a Linux system to function. Among others, util-linux contains the fdisk configuration tool and the login program. Multiple flaws were found in the way the mount and umount commands performed mtab file updates. A local, unprivileged user allowed to mount or unmount file systems could use these flaws to corrupt the mtab file and create a stale lock file, preventing other users from mounting and unmounting file systems.
