If problems still persist, please make note of it in this bug report. subversion-1.8.11-1.fc21 has been pushed to the Fedora 21 stable repository. If problems still persist, please make note of it in this bug report. Analysis ======== In the code of subversion there missing sanity check for repository path at various places, sending crafted report request causes crash because of NULL pointer dereference. In function dav_svn__get_deleted_rev_report(const dav_resource *resource, const apr_xml_doc *doc, ap_filter_t *output) reaching this line in the code of function dav_svn__get_deleted_rev_report() would cause a crash if repository path is not set or is NULL causing NULL pointer dereference abs_path = svn_path_join(resource->info->repos_path, rel_path, resource->pool); Similar problem exists in various other places of the subversion code.
