Software description
apache2 - Apache HTTP server Details

trailers to replace HTTP headers during request processing. A remote attacker
could possibly use this issue to bypass RequestHeaders directives.

HTTP Content-Type headers. A remote attacker could use this issue to cause the

affected Ubuntu 14.04 LTS and Ubuntu 14.10. (CVE-2014-3581)
Teguh P. Alko discovered that the mod_proxy_fcgi module incorrectly handled
long response headers. A remote attacker could use this issue to cause the
server to stop responding, leading to a denial of service. This issue only
affected Ubuntu 14.10. (CVE-2014-3583)
It was discovered that the mod_lua module incorrectly handled different
arguments within different contexts. A remote attacker could possibly use this
issue to bypass intended access restrictions. This issue only affected Ubuntu

Guido Vranken discovered that the mod_lua module incorrectly handled a
specially crafted websocket PING in certain circumstances. A remote attacker
