[Backports-security-announce] Security update for webauth



Russ Allbery uploaded new packages for webauth which fixed the following
security problem:

CVE-2009-2945

    WebAuth 3.5.5 introduced a new method to probe for browser cookie
    support in the WebLogin script.  Under rare circumstances, a browser
    may present the test cookie when loading the login form but then not
    present the cookie when submitting the form.  Because the form is
    converted to a GET, the user's password becomes part of the URL and
    therefore enters the browser history, where it may be exposed by
    shared use of the system or through snooping attacks on browser
    history.  It is also exposed in the web server logs of the WebLogin
    server.  If the WebLogin confirmation page is enabled, the URL
    containing the user's password may also become the referrer and be
    sent by the browser in the referrer header to the web site to which
    the user was authenticating, where it would be seen by that web server
    and possibly logged in its server logs.

This problem affects the webauth-weblogin package.  Only that component of
WebAuth is affected.  The Apache modules used on individual
WebAuth-protected servers do not have to be updated.

For the lenny-backports distribution this problem has been fixed in
version 3.6.2-1~bpo50+1.

For the unstable distribution, this problem has been fixed in version
3.6.2-1.

For the stable distribution, this problem will be fixed in 3.6.0-1+lenny1,
which is being proposed for the next stable update.

Upgrade instructions
--------------------
  
If you don't use pinning [1] you have to update the package manually via
apt-get -t lenny-backports install webauth-weblogin.
  
We recommend to pin the backports repository to 200 so that new versions
of installed backports will be installed automatically.
  
    Package: *
    Pin: release a=lenny-backports
