Updated subversion packages fix security vulnerabilities

Updated subversion packages fix security vulnerabilities: 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-2016-2167). 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 (CVE-2016-2168).
