EulerOS 2.0 SP3 : gdm (EulerOS-SA-2021-1787)

high Nessus Plugin ID 149178

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

According to the versions of the gdm package installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

- A vulnerability was discovered in gdm before 3.31.4.
When timed login is enabled in configuration, an attacker could bypass the lock screen by selecting the timed login user and waiting for the timer to expire, at which time they would gain access to the logged-in user's session.(CVE-2019-3825)

- The daemon in GDM through 3.29.1 does not properly unexport display objects from its D-Bus interface when they are destroyed, which allows a local attacker to trigger a use-after-free via a specially crafted sequence of D-Bus method calls, resulting in a denial of service or potential code execution.(CVE-2018-14424)

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

Solution

Update the affected gdm packages.
