This update for permissions fixes the following issues :

CVE-2019-3688: Changed wrong ownership in /usr/sbin/pinger to root:squid which could have allowed a squid user to gain persistence by changing the binary (bsc#1093414).

CVE-2019-3690: Fixed a privilege escalation through untrusted symbolic links (bsc#1150734).

Fixed a regression which caused segmentation fault (bsc#1157198).

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.
