This update for sudo fixes the following issues: CVE-2017-1000367 :
Due to incorrect assumptions in /proc/[pid]/stat parsing, a local attacker can pretend that his tty is any file on the filesystem, thus gaining arbitrary file write access on SELinux-enabled systems. [bsc#1039361]
Fix FQDN for hostname. [bsc#1024145]
Filter netgroups, they aren’t handled by SSSD.
[bsc#1015351]
Fix problems related to ‘krb5_ccname’ option [bsc#981124]
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.
