The version of Subversion Server installed on the remote host is prior to version 1.8.2. It is, therefore, affected by multiple vulnerabilities :
A repository corruption vulnerability related to ‘FileSystem atop the FileSystem’ (FSFS) repositories and handling packed revision properties editing.
(CVE-2013-4246)
A symlink privilege escalation vulnerability in ‘svnwcsub.py’ and ‘irkerbridge.py’ exists when the
–pidfile option is used. The option creates temporary files insecurely, and may allow a local attacker to use a symlink attack against a pid file to gain elevated privileges. (CVE-2013-7393)
