CVE-2013-1847 Subversion (mod_dav_svn): DoS (crash) via LOCK requests against a non-existent URL
Last modified: 2015-11-24 10:30:54 EST
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.
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.
