Apache mod_dav_svn denial of service in propfind request

I checked whether this exploit works, and it did against the 1.5.1
ubuntu hardy-backport package of subversion and libapache2-svn. It also
worked against the latest trunk checkout of subversion.

When using this exploit, ram usage increases rapidly. When all the swap
space is used the system hangs.

I think this issue is already discussed in the "Memory leak with 1.6.x
clients" thread from dev_at_subversion.tigris.org, but I'm not sure.

Yours sincerely,
Jorn van Engelen
