It was found that Subversion's mod_dav_svn Apache HTTPD server module will crash in some circumstances when a LOCK request is made against a non-existent URL. This can lead to DoS. The vulnerability can be triggered by doing a LOCK request against a URL for a path that does not exist in the repository or an invalid activity URL where authentication is not required for the LOCK method. Acknowledgements: Red Hat would like to thank the Apache Subversion project for reporting this issue. Upstream acknowledges Philip Martin and Ben Reser as the original reporter of this flaw.
