CVE-2002-0839 is a vulnerability of currently unknown severity. The shared memory scoreboard in the HTTP daemon for Apache 1.3.x before 1.3.27 allows any user running as the Apache UID to send a SIGUSR1 signal to any process as root, resulting in a denial of service (process kill) or possibly other behaviors that would not normally be allowed, by modifying the parent[].pid and parent[].last_rtime segments in the scoreboard.. EPSS estimates a 0.94% chance of exploitation in the next 30 days.
