  • mod_headers rules could be bypassed via chunked requests. Adds 'MergeTrailers' directive to restore legacy behavior. (bsc#871310, CVE-2013-5704)
  • An empty value in Content-Type could lead to a crash through a null pointer dereference and a denial of service. (bsc#899836, CVE-2014-3581)
  • Remote attackers could bypass intended access restrictions in mod_lua LuaAuthzProvider when multiple Require directives with different arguments are used. (bsc#909715, CVE-2014-8109)
