CentOS 7 : util-linux (CESA-2017:0907)

medium Nessus Plugin ID 99380

Language:

Synopsis

The remote CentOS host is missing one or more security updates.

Description

An update for util-linux is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

The util-linux packages contain a large variety of low-level system utilities that are necessary for a Linux system to function. Among others, these include the fdisk configuration tool and the login program.

Security Fix(es) :

* A race condition was found in the way su handled the management of child processes. A local authenticated attacker could use this flaw to kill other processes with root privileges under specific conditions.
(CVE-2017-2616)

Red Hat would like to thank Tobias Stockmann for reporting this issue.

Bug Fix(es) :

* The 'findmnt --target ' command prints all file systems where the mount point directory is . Previously, when used in the chroot environment, 'findmnt --target ' incorrectly displayed all mount points. The command has been fixed so that it now checks the mount point path and returns information only for the relevant mount point.
(BZ#1414481)

Solution

Update the affected util-linux packages.
