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 . - CVE-2019-3690: Fixed a privilege escalation through untrusted symbolic links . Other issue addressed: - Corrected a badly constracted file which could have allowed treating of the shell environment as permissions files . - Fixed a regression which caused sagmentation fault .
