[BSA-031] Security Update for squid3

Julien Danjou uploaded new packages for squid3 which fixed the following
security problems:

  When IPv6 DNS resolution is not enabled, accesses an invalid socket
  during an IPv4 TCP DNS query, which allows remote attackers to cause a
  denial of service (assertion failure and daemon exit) via vectors that
  trigger an IPv4 DNS response with the TC bit set.

  Due to an internal error in string handling Squid is vulnerable to a
  denial of service attack when processing specially crafted requests.
  This problem allows any trusted client to perform a denial of service
  attack on the Squid service.

For the lenny-backports distribution the problems have been fixed in
version 3.1.6-1.2~bpo50+1.

If you don't use pinning (see [1]) you have to update the package
manually via "apt-get -t lenny-backports install <packagelist>" with
the packagelist of your installed packages affected by this update.
[1] <http://backports.debian.org/Instructions>

We recommend to pin (in /etc/apt/preferences) the backports repository to
200 so that new versions of installed  backports will be installed

  Package: *
  Pin: release a=lenny-backports
  Pin-Priority: 200
