many features that CVS users often wish they had.");

project identifies the following problems:

CVE-2016-2167 
Daniel Shahaf and James McCoy discovered that an implementation
error in the authentication against the Cyrus SASL library would
permit a remote user to specify a realm string which is a prefix of
the expected realm string and potentially allowing a user to
authenticate using the wrong realm.

CVE-2016-2168 
Ivan Zhakov of VisualSVN discovered a remotely triggerable denial
of service vulnerability in the mod_authz_svn module during COPY or
MOVE authorization check. An authenticated remote attacker could
take advantage of this flaw to cause a denial of service
(Subversion server crash) via COPY or MOVE requests with specially
crafted header.");
