This only affects use cases where source packages are downloaded via this command, it does not affect regular Debian package installation and upgrading. (CVE-2014-0478)

It was discovered that APT incorrectly handled the Verify-Host configuration option. If a remote attacker were able to perform a man-in-the-middle attack, this flaw could potentially be used to steal repository credentials. This only relevant for systems that use APT sources on https connections (requires the apt-transport-https package to be installed). (CVE-2011-3634)

For Debian 6 Squeeze, these issues have been fixed in apt version 0.8.10.3+squeeze2");
