It is recommended that administrators running util-linux-ng check for an updated version of the software for their operating system. - --------------------------BEGIN INCLUDED TEXT-------------------- - -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Low: util-linux-ng security, bug fix and enhancement update Advisory ID: RHSA-2013:0517-02 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2013-0517.html Issue date: 2013-02-21 CVE Names: CVE-2013-0157 ===================================================================== 1. Summary: Updated util-linux-ng packages that fix one security issue, several bugs, and add various enhancements are now available for Red Hat Enterprise Linux 6. The Red Hat Security Response Team has rated this update as having low security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. 2. Relevant releases/architectures: Red Hat Enterprise Linux Desktop (v. 6) - i386, x86_64 Red Hat Enterprise Linux Desktop Optional (v. 6) - i386, x86_64 Red Hat Enterprise Linux HPC Node (v. 6) - x86_64 Red Hat Enterprise Linux HPC Node Optional (v. 6) - x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64 3. Description: The util-linux-ng packages contain a large variety of low-level system utilities that are necessary for a Linux operating system to function. An information disclosure flaw was found in the way the mount command reported errors. A local attacker could use this flaw to determine the existence of files and directories they do not have access to. (CVE-2013-0157) These updated util-linux-ng packages include numerous bug fixes and enhancements. Space precludes documenting all of these changes in this advisory. Users are directed to the Red Hat Enterprise Linux 6.4 Technical Notes, linked to in the References, for information on the most significant of these changes. All users of util-linux-ng are advised to upgrade to these updated packages, which contain backported patches to correct these issues and add these enhancements. 4. Solution: Before applying this update, make sure all previously-released errata relevant to your system have been applied. This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/knowledge/articles/11258 5. Bugs fixed (http://bugzilla.redhat.com/): 679833 - [RFE] tailf should support `-n 0` 783514 - Documentation for default barrier setting for EXT3 filesystems in mount manpage is wrong 790728 - blkid ignores swap UUIDs if the first byte is a zero byte 818621 - lsblk should not open device it prints info about 839281 - manpage: mount option inode_readahead for ext4 should be inode_readahead_blks 892330 - CVE-2013-0157 util-linux: mount folder existence information disclosure 6.
