Apache httpd 2.0.59 and 2.2.4, with the Prefork MPM module, allows local users to cause a denial of service via certain code sequences executed in a worker process that (1) stop request processing by killing all worker processes and preventing creation of replacements or (2) hang the system by forcing the master process to fork an arbitrarily large number of worker processes. NOTE: This might be an inherent design limitation of Apache with respect to worker processes in hosted environments.

Security readout for executives and security teams

This is an old Apache httpd denial-of-service issue affecting specific 2.0.59 and 2.2.4 deployments using Prefork MPM. A local user able to run code inside a worker process could disrupt request handling or exhaust the server through excessive worker creation. Exposure is most plausible on legacy Apache httpd 2.0.59 or 2.2.4 systems using Prefork MPM, especially shared-hosting or multi-user environments where untrusted local users can execute code in web worker contexts. Treat this as a legacy shared-hosting availability risk. Prioritize systems still running the named Apache versions with local or tenant code execution, but do not treat it as proven internet-scale exploitation from the supplied evidence. Mitigation focus: Identify any Apache httpd 2.0.59 or 2.2.4 instances using Prefork MPM.; Check Apache or OS vendor guidance for supported updates or configuration changes.; Restrict untrusted local code execution in Apache worker contexts..
