Apache Traffic Server 2.0.x and 3.0.x before 3.0.4 and 3.1.x before 3.1.3 does not properly allocate heap memory, which allows remote attackers to cause a denial of service (daemon crash) via a long HTTP Host header.

Security readout for executives and security teams

A remote request with an overly long HTTP Host header can crash vulnerable Apache Traffic Server daemons. For organizations using Traffic Server as a proxy or cache, this is primarily an availability risk: affected services may stop handling traffic until restarted or remediated. Exposure is limited to environments running the named Apache Traffic Server versions on reachable HTTP or proxy-facing interfaces. The provided source bundle does not identify affected CPEs, deployment prevalence, or dependent products. Treat this as a service availability fix for any organization still running the old Traffic Server branches. It is not marked KEV in the bundle, but exposed proxy infrastructure should not remain vulnerable to remote crash conditions. Mitigation focus: Upgrade affected 3.0.x deployments to 3.0.4 or later.; Upgrade affected 3.1.x deployments to 3.1.3 or later.; Retire or replace 2.0.x instances according to Apache guidance..
