========================================================================== Ubuntu Security Notice USN-3934-1 April 03, 2019
policykit-1 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:
PolicyKit could allow unintended access.
Software Description: - policykit-1: framework for managing administrative policies and privileges
Details:
It was discovered that PolicyKit incorrectly relied on the fork() system call in the Linux kernel being atomic. A local attacker could possibly use this issue to gain access to services that have cached authorizations.
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 18.10: libpolkit-backend-1-0 0.105-21ubuntu0.4 policykit-1 0.105-21ubuntu0.4
Ubuntu 18.04 LTS: libpolkit-backend-1-0 0.105-20ubuntu0.18.04.5 policykit-1 0.105-20ubuntu0.18.04.5
Ubuntu 16.04 LTS: libpolkit-backend-1-0 0.105-14.1ubuntu0.5 policykit-1 0.105-14.1ubuntu0.5
Ubuntu 14.04 LTS: libpolkit-backend-1-0 0.105-4ubuntu3.14.04.6 policykit-1 0.105-4ubuntu3.14.04.6
After a standard system update you need to reboot your computer to make all the necessary changes.
