DISPUTED An issue was discovered in systemd 253. An attacker can
modify the contents of past events in a sealed log file and then adjust the
file such that checking the integrity shows no error, despite
modifications. NOTE: the vendor reportedly sent “a reply denying that any
of the finding was a security vulnerability.”
