cache_util.c in the mod_cache module in Apache HTTP Server (httpd), when caching is enabled and a threaded Multi-Processing Module (MPM) is used, allows remote attackers to cause a denial of service (child processing handler crash) via a request with the (1) s-maxage, (2) max-age, (3) min-fresh, or (4) max-stale Cache-Control headers without a value.

Security readout for executives and security teams

This flaw can let a remote requester crash part of an Apache HTTP Server process when caching is enabled in a specific threaded configuration. The business impact is service disruption, not data theft or remote code execution based on the supplied sources. Exposure is most likely on legacy Apache HTTP Server 2.0 or 2.2 deployments using mod_cache, enabled caching, and a threaded MPM. Systems without mod_cache caching or without threaded MPM use are not clearly exposed from the supplied evidence. Treat this as a legacy availability risk. It is important for exposed Apache caching servers, but lower urgency than code execution or data disclosure issues unless the affected service is business-critical. Mitigation focus: Check Apache and OS vendor advisories for the fixed package or version.; Prioritize upgrades on internet-facing Apache servers using mod_cache.; Disable caching if mod_cache is not operationally required..
