Description

A flaw was found in the mod_proxy_ajp module of httpd. When processing AJP (Apache JServ Protocol) messages, the server fails to properly check if a string is null-terminated before attempting to read it, allowing an attacker or a malformed request to cause a heap-based buffer over-read. This issue potentially leads to memory disclosure and a denial of service.
