Description

Apache2 updated to fix four security issues and one non-security bug.

The following vulnerabilities have been fixed :

  • 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)

  • Remote attackers could cause a denial of service (child-process crash) by sending a crafted WebSocket Ping frame after a Lua script has called the wsupgrade function. (bsc#918352, CVE-2015-0228)

The update package also includes non-security fixes. See advisory for details.

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