Description Jan Lieskovsky 2011-05-30 16:56:01 UTC 
An infinite loop was found in the way mod_dav_svn module of the subversion
concurrent version control system processed certain data sets, when
SVNPathAuthz configuration directive with value of 'short_circuit' was used.
A remote attacker could use this flaw to cause the httpd child process to
consume excessive amount of system memory.
