- A flaw exists in the 'mod_dav_svn' that is triggered when handling node properties. (CVE-2013-1845)
- A NULL pointer dereference exists in the 'mod_dav_svn' module, triggered during the handling of a crafted Log REPORT request, URL lock request, LOCK request against non-existent URL, and URL PROPFIND request. (CVE-2013-1846, CVE-2013-1847, CVE-2013-1849)
