Red Hat Security Advisory 2015-1666-01 - The httpd packages provide the Apache HTTP Server, a powerful, efficient, and extensible web server. Multiple flaws were found in the way httpd parsed HTTP requests and responses using chunked transfer encoding. A remote attacker could use these flaws to create a specially crafted request, which httpd would decode differently from an HTTP proxy software in front of it, possibly leading to HTTP request smuggling attacks. It was discovered that in httpd 2.4, the internal API function ap_some_auth_required() could incorrectly indicate that a request was authenticated even when no authentication was used. An httpd module using this API function could consequently allow access that should have been denied.

Ubuntu Security Notice 2523-1 - 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. 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. Various other issues were also addressed.
