What is CVE-2012-0954?
APT 0.7.x before 0.7.25 and 0.8.x before 0.8.16, when using the apt-key net-update to import keyrings, relies on GnuPG argument order and does not check GPG subkeys, which might allow remote attackers to install altered packages via a man-in-the-middle (MITM) attack.  NOTE: this vulnerability exists because of an incomplete fix for CVE-2012-3587..
