Affected Products:

An update that solves one vulnerability and has three fixes is now available.

Description:

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).
