Astra Linux – Vulnerability in Systemd

It was discovered that a Systemd service that uses the DynamicUser property can obtain new privileges by executing SUID binaries. This allows the service to create binaries belonging to the transient group, with the setgid bit set. A local attacker could exploit this flaw to access resources that...
