Descriptions

The lua_websocket_read function in lua_request.c in the mod_lua module in the Apache HTTP Server through 2.4.12 allows remote attackers to cause a denial of service (child-process crash) by sending a crafted WebSocket Ping frame after a Lua script has called the wsupgrade function.

La función lua_websocket_read en lua_request.c en el módulo mod_lua en Apache HTTP Server hasta 2.4.12 permite a atacantes remotos causar una denegación de servicio (caída del proceso hijo) mediante el envío de un Frame WebSocket Ping manipulado después de que una secuencia de comandos Lua haya llamado a la función wsupgrade.

A denial of service flaw was found in the way the mod_lua httpd module processed certain WebSocket Ping requests. A remote attacker could send a specially crafted WebSocket Ping packet that would cause the httpd child process to crash.
