A vulnerability classified as problematic has been found in Apache HTTP Server up to 2.4.12 (Web Server). This affects the function wsupgrade of the file lua_request.c of the component mod_lua. The manipulation with an unknown input leads to a input validation vulnerability. CWE is classifying the issue as CWE-20. The product receives input or data, but it does not validate or incorrectly validates that the input has the properties that are required to process the data safely and correctly. This is going to have an impact on availability. The summary by CVE is:

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.

The weakness was disclosed 03/07/2015 (GitHub Repository). It is possible to read the advisory at github.com. This vulnerability is uniquely identified as CVE-2015-0228 since 11/18/2014.
