Description

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.

Affected

Our own answer: ranges merged, affected separated from platform-only, with confidence and review flags.

1.3.0 ≤ v < 1.3.27
Affected range stops below 1.3.27, so it looks safe — our inference, not a vendor statement
