SUSE SLED15 / SLES15 Security Update : gdm (SUSE-SU-2019:0527-1)

medium Nessus Plugin ID 122581

Language:

Synopsis

The remote SUSE host is missing one or more security updates.

Description

This update for gdm fixes the following issues :

Security issue fixed :

CVE-2019-3825: Fixed a lock screen bypass when timed login was enabled (bsc#1124628).

Other issues fixed: GLX applications do not work well when the proprietary nvidia driver is used with a wayland session. Because of that this update disables wayland on that hardware (bsc#1112578).

Fixed an issue where gdm restart fails to kill user processes (bsc#1112294 and bsc#1113245).

Fixed a System halt in the screen with message 'End of ORACLE section' (bsc#1120307).

Fixed an issue which did not allow the returning to text console when gdm is stopped (bsc#1113700).

Fixed an issue which was causing system hang during the load of gdm (bsc#1112578).

Note that Tenable Network Security has extracted the preceding description block directly from the SUSE security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
