Description

apt-get in apt before 0.7.21 does not check for the correct error code from gpgv, which causes apt to treat a repository as valid even when it has been signed with a key that has been revoked or expired, which might allow remote attackers to trick apt into installing malicious repositories.

Affected products

Debian Advanced Package Tool: through 0.7.20; 0.7.0, 0.7.1, 0.7.2, 0.7.2-0.1, 0.7.10, 0.7.11 (+18)
Debian apt: 0.0.1, 0.0.2, 0.0.3, 0.0.4, 0.0.5, 0.0.6 (+149)
