apache2

The Discovery 

Several remotely and easily exploitable vulnerabilities have been identified in the widely used apache2 server. These issues involve the mishandling of inputs and the potential to inject malicious code. Another bug affects apache2's HTTP/2 module and could lead to denial-of-service attacks by overwhelming the server with endless data streams. A mod_macro module's memory management flaw allows remote attackers to crash the server, resulting in a denial-of-service attack.
