SuSE: New subversion packages fix remote denial of service

Subversion was updated to fix several security issues: The mod_dav_svn Apache HTTPD server module can be crashed though when asked to deliver baselined WebDAV resources. The mod_dav_svn Apache HTTPD server module can trigger a loop which consumes all available memory on the system. The mod_dav_svn Apache HTTPD server module may leak to remote users the file contents of files configured to be unreadable by those users. Remote attackers could crash an svn server by causing a NULL deref. Updated packages are available from download.opensuse.org.
