   An update that solves two vulnerabilities and has three
   fixes is now available.

Description:

   This update for permissions fixes the following issues:

   Security issues fixed:

   - 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).

   Other issue addressed:

   - Corrected a badly constracted file which could have allowed treating of
     the shell environment as permissions files (bsc#1097665,bsc#1047247).
   - Fixed a regression which caused sagmentation fault (bsc#1157198).
