Description

A flaw was found in the mod_proxy_ajp module of httpd. When processing AJP (Apache JServ Protocol) messages, the ajp_parse_data function attempts to read data beyond the allocated buffer size, 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.
