> The Geronimo project has learned of a security vulnerability in the 
> Apache Tomcat Webdav Servlet implementation. If you use a Tomcat 
> configuration of Geronimo and configure a write-enabled Webdav servlet, 
> you may be affected by this vulnerability. If you do not configure the 
> Webdav servlet or configure read-only Webdav servlets, you are not 
> impacted by this vulnerability. Jetty configurations of Geronimo are not 
> affected by this vulnerability. 
> This vulnerability impacts all Geronimo releases. Up to and including 
> Geronimo 2.0.2.
> For specific information regarding the Tomcat issue, see http://mail-archives.apache.org/mod_mbox/tomcat-users/200710.mbox/%3c47135C2D.1000705@apache.org%3e
> By default, Geronimo releases do not use the Webdav servlet. However, it 
> is possible for the Webdav Servlet to be configured or referenced by a 
> user-written application. 
> The Webdav Servlet could be explicitly configured in a web.xml 
> <http://web.xml/> deployment descriptor as follows:
>          ...
>     <servlet>
>         <servlet-name>webdav</servlet-name>
>         <servlet-class>org.apache.catalina.servlets.WebdavServlet</servlet-class>
>         <init-param>
>           <param-name>readonly</param-name>
>           <param-value>false</param-value>
>         </init-param>
>     </servlet>
> Alternatively, a user's application could extend the WebdavServlet, for 
> example:
>         import org.apache.catalina.servlets.WebdavServlet;
>         public class MyServlet extends WebdavServlet {
>    ...
>    
> If you configure a write-enabled Webdav servlet, we recommend that you:
>   - Disable write access to the Webdav Servlet until this problem has 
> been fixed, or
>   - Limit access to the Webdav servlet to only trusted users.
> This vulnerability will be fixed in the next release of Geronimo (2.0.3 
> and/or 2.1).
