EulerOS 2.0 SP8 : trousers (EulerOS-SA-2020-2160)

high Nessus Plugin ID 141008

Synopsis

The remote EulerOS host is missing multiple security updates.

Description

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

- An issue was discovered in TrouSerS through 0.3.14. If the tcsd daemon is started with root privileges instead of by the tss user, it fails to drop the root gid privilege when no longer needed.(CVE-2020-24330)

- An issue was discovered in TrouSerS through 0.3.14. If the tcsd daemon is started with root privileges, the tss user still has read and write access to the /etc/tcsd.conf file (which contains various settings related to this daemon).(CVE-2020-24331)

- An issue was discovered in TrouSerS through 0.3.14. If the tcsd daemon is started with root privileges, the creation of the system.data file is prone to symlink attacks. The tss user can be used to create or corrupt existing files, which could possibly lead to a DoS attack.(CVE-2020-24332)

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 trousers packages.
