NewStart CGSL MAIN 6.02 : systemd Multiple Vulnerabilities (NS-SA-2022-0055)

high Nessus Plugin ID 160827

Synopsis

The remote NewStart CGSL host is affected by multiple vulnerabilities.

Description

The remote NewStart CGSL host, running version MAIN 6.02, has systemd packages installed that are affected by multiple vulnerabilities:

- An issue was discovered in button_open in login/logind-button.c in systemd before 243. When executing the udevadm trigger command, a memory leak may occur. (CVE-2019-20386)

- In systemd before v242-rc4, it was discovered that pam_systemd does not properly sanitize the environment before using the XDG_SEAT variable. It is possible for an attacker, in some particular configurations, to set a XDG_SEAT environment variable which allows for commands to be checked against polkit policies using the allow_active element rather than allow_any. (CVE-2019-3842)

- systemd through v245 mishandles numerical usernames such as ones composed of decimal digits or 0x followed by hex digits, as demonstrated by use of root privileges when privileges of the 0x0 user account were intended. NOTE: this issue exists because of an incomplete fix for CVE-2017-1000082. (CVE-2020-13776)

- basic/unit-name.c in systemd prior to 246.15, 247.8, 248.5, and 249.1 has a Memory Allocation with an Excessive Size Value (involving strdupa and alloca for a pathname controlled by a local attacker) that results in an operating system crash. (CVE-2021-33910)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade the vulnerable CGSL systemd packages. Note that updated packages may not be available yet. Please contact ZTE for more information.
