Description Jan Lieskovsky 2013-07-19 08:12:38 UTC
A denial of service flaw was found in the way mod_dav_svn module of Subversion (SVN), a concurrent version control system, used to process certain MOVE, COPY, or DELETE HTTP requests (requests that originated or targeted against a revision root). A remote attacker, with commit access / privileges could use this flaw to cause denial of service (depending on the Apache httpd web server configuration either child assertion failure or crash [prefork MPM configuration] or failure to handle other requests, originally scheduled to be handled within the same thread [threaded MPM configuration] due to a process termination) by issuing a specially-crafted SVN commit request.

Vulnerable package versions:
* Subversion HTTPD servers 1.7.0 through 1.7.10 (inclusive)
* Subversion HTTPD servers 1.8.0 (including 1.8.0 release candidates).
* svnserve (any version) is not vulnerable.
* Subversion 1.6.x is not vulnerable.
