Description

Martin Holst Swende discovered that the mod_headers module allowed HTTP trailers to replace HTTP headers during request processing. A remote attacker could possibly use this issue to bypass RequestHeaders directives. (CVE-2013-5704)

Mark Montague discovered that the mod_cache module incorrectly handled empty HTTP Content-Type 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 14.04 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 14.10. (CVE-2014-8109)

Guido Vranken discovered that the mod_lua module incorrectly handled a specially crafted websocket PING in certain circumstances. A remote attacker could possibly use this issue to cause the server to stop responding, leading to a denial of service. This issue only affected Ubuntu 14.10. (CVE-2015-0228).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
