CVE-2012-0214

The pkgAcqMetaClearSig::Failed method in apt-pkg/acquire-item.cc in
Advanced Package Tool (APT) 0.8.11 through 0.8.15.10 and 0.8.16 before
0.8.16~exp13, when updating from repositories that use InRelease files,
allows man-in-the-middle attackers to install arbitrary packages by
preventing a user from downloading the new InRelease file, which leaves the
original InRelease file active and makes it more difficult to detect that
the Packages file is modified and unsigned.
