CVE-2012-0954 Information

Description

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.
