========================================================================== Ubuntu Security Notice USN-3938-1 April 08, 2019
systemd vulnerability ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 18.10 - Ubuntu 18.04 LTS - Ubuntu 16.04 LTS - Ubuntu 14.04 LTS
Summary:
The systemd PAM module could be used to gain additional PolicyKit privileges.
Software Description: - systemd: system and service manager
Details:
Jann Horn discovered that pam_systemd created logind sessions using some parameters from the environment. A local attacker could exploit this in order to spoof the active session and gain additional PolicyKit privileges.
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 18.10: libpam-systemd 239-7ubuntu10.12
Ubuntu 18.04 LTS: libpam-systemd 237-3ubuntu10.19
Ubuntu 16.04 LTS: libpam-systemd 229-4ubuntu21.21
Ubuntu 14.04 LTS: libpam-systemd 204-5ubuntu20.31
In general, a standard system update will make all the necessary changes.
