DESCRIPTION:
Debian has issued an update for dpkg. This fixes two vulnerabilities,
which can be exploited by malicious people to manipulate certain data
or compromise a vulnerable system.

1) The dpkg-source component does not properly handle paths in
patches when unpacking version "3.0 quilt" source packages, which can
be exploited to modify arbitrary files outside of the intended
destination directory.

2) The dpkg-source component incorrectly follows symlinks in the
".pc" directory when unpacking version "3.0 quilt" source packages,
which can be exploited to modify arbitrary files outside of the
intended destination directory.

SOLUTION:
Apply updated packages via the apt-get package manager.
