CVE-2013-6438  (opens in a new tab)
CWE-20  (opens in a new tab)

How to fix?

Upgrade Debian:10 apache2 to version 2.4.9-1 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream apache2 package and not the apache2 package as distributed by Debian. See How to fix? for Debian:10 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.
