How to fix?

This issue was patched in ALAS-2014-331.

NVD Description

Note: Versions mentioned in the description apply only to the upstream httpd-debuginfo package and not the httpd-debuginfo package as distributed by Amazon-Linux. See How to fix? for Amazon-Linux:2018.03 relevant fixed versions and status.

The dav_xml_get_cdata function in main/util.c in the mod_dav module in the Apache HTTP Server before 2.4.8 does not properly remove whitespace characters from CDATA sections, which allows remote attackers to cause a denial of service (daemon crash) via a crafted DAV WRITE request.
