Synopsis :

The remote FreeBSD host is missing one or more security-related
updates.

Description :

Subversion team reports :

Subversion's mod_dav_svn Apache HTTPD server module will dereference a
NULL pointer if asked to deliver baselined WebDAV resources.

This can lead to a DoS. An exploit has been tested, and tools or users
have been observed triggering this problem in the wild.

Subversion's mod_dav_svn Apache HTTPD server module may in certain
scenarios enter a logic loop which does not exit and which allocates
memory in each iteration, ultimately exhausting all the available
memory on the server.

This can lead to a DoS. There are no known instances of this problem
being observed in the wild, but an exploit has been tested.

Subversion's mod_dav_svn Apache HTTPD server module may leak to remote
users the file contents of files configured to be unreadable by those
users.

There are no known instances of this problem being observed in the
wild, but an exploit has been tested.
