Synopsis :

The remote Amazon Linux AMI host is missing a security update.

Description :

The is_this_legal function in mod_dontdothat for Apache Subversion
1.4.0 through 1.7.13 and 1.8.0 through 1.8.4 allows remote attackers
to bypass intended access restrictions and possibly cause a denial of
service (resource consumption) via a relative URL in a REPORT request.

The get_parent_resource function in repos.c in mod_dav_svn Apache
HTTPD server module in Subversion 1.7.11 through 1.7.13 and 1.8.1
through 1.8.4, when built with assertions enabled and
SVNAutoversioning is enabled, allows remote attackers to cause a
denial of service (assertion failure and Apache process abort) via a
non-canonical URL in a request, as demonstrated using a trailing /.
