SUSE: 2019:2668-1 Important: Sudo Privilege Escalation Fix

This update for sudo provides the following fix: Security issue fixed: - CVE-2019-14287: Fixed an issue where a user with sudo privileges that allowed them to run commands with an arbitrary uid, could run commands as root, despite being forbidden to do so in sudoers (bsc#1153674). Other issues fixed: - Cache resolved group names as calling getgrgid() is expensive and on systems connected to AD with many users, groups or sudo rules it causes sudo to take a long time to run (bsc#1068003). - Disable insults by default at build time. For new installations this was done via sudoers file, but when upgrading from previous versions it would accidentally be enabled (bsc#1053911). - Enable support for zlib compressed I/O logs (bsc#1058297).
