Patrick Matthäi <pmatthaei> uploaded new packages for znc which fixed
the following security problems:

CVE-2010-2934
    Multiple unspecified vulnerabilities in ZNC 0.092 allow remote
    attackers to cause a denial of service (exception and daemon crash)
    via unknown vectors related to "unsafe substr() calls."

CVE-2010-2812
    Client.cpp in ZNC 0.092 allows remote attackers to cause a denial
    of service (exception and daemon crash) via a PING command that
    lacks an argument.

For the lenny-backports distribution the problems have been fixed in
version 0.092-3~bpo50+1.


Upgrade instructions
--------------------

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] <https://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
automatically.
