Ubuntu Security Notice USN-5067-1
Posted Sep 8, 2021
Authored by Ubuntu | Site security.ubuntu.com

Ubuntu Security Notice 5067-1 - Jakub Hrozek discovered that SSSD incorrectly handled file permissions. A local attacker could possibly use this issue to read the sudo rules available for any user. This issue only affected Ubuntu 18.04 LTS. It was discovered that SSSD incorrectly handled Group Policy Objects. When SSSD is configured with too strict permissions causing the GPO to not be readable, SSSD will allow all authenticated users to login instead of being denied, contrary to expectations. This issue only affected Ubuntu 18.04 LTS. Various other issues were also addressed.
