Debian DLA-71-1 : apache2 security update

Description

This update fixes two security issues with apache2.

CVE-2013-5704

Disable the possibility to replace HTTP headers with HTTP trailers as this could be used to circumvent earlier header operations made by other modules. This can be restored with a new MergeTrailers directive.

CVE-2014-3581

Fix denial of service where Apache can segfault when mod_cache is used and when the cached request contains an empty Content-Type header.

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