CVE-2019-3842
HIGH7.0EPSS 0.10%systemd - security update
Published: 4/9/2019Modified: 4/28/2026
Description
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".
