CVE-2019-3842 (opens in a new tab)Amendment
The SLES security team deemed this advisory irrelevant for SLES:15.0.
NVD Description
Note: Versions mentioned in the description apply only to the upstream nss-myhostname package and not the nss-myhostname package as distributed by SLES.
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".
