Description

This update for util-linux fixes a number of bugs and two security issues. The following security bugs were fixed :

  • CVE-2016-5011: Infinite loop DoS in libblkid while parsing DOS partition (bsc#988361)

  • CVE-2017-2616: In su with PAM support it was possible for local users to send SIGKILL to selected other processes with root privileges (bsc#1023041).

The update package also includes non-security fixes. See advisory for details.

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
