"An assertion failure flaw was found in the way the SVN server
processed certain requests with dynamically evaluated revision
numbers. A remote attacker could use this flaw to cause the SVN server
(both svnserve and httpd with the mod_dav_svn module) to crash.
(CVE-2015-0248)

It was found that the mod_dav_svn module did not properly validate the
svn:author property of certain requests. An attacker able to create
new revisions could use this flaw to spoof the svn:author property.
(CVE-2015-0251)

It was found that when an SVN server (both svnserve and httpd with the
mod_dav_svn module) searched the history of a file or a directory, it
would disclose its location in the repository if that file or
directory was not readable (for example, if it had been moved).
(CVE-2015-3187)

After installing the updated packages, for the update to take effect,
you must restart the httpd daemon, if you are using mod_dav_svn, and
the svnserve daemon, if you are serving Subversion repositories via
the svn:// protocol."
