3. Description:
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 Stöckmann for reporting this issue.
Bug Fix(es):
* The “findmnt –target <path>” command prints all file systems where the
mount point directory is <path>. Previously, when used in the chroot
environment, “findmnt –target <path>” 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)
