Security Flaw in APT Package Manager by Ubuntu Affects Key Management

CVE-2012-3587

Summary

A security flaw in APT versions prior to 0.7.25 and 0.8.16 allows for exploitation through the improper handling of GnuPG argument order. This vulnerability occurs when using the apt-key net-update command to import keyrings, failing to verify GPG subkeys. As a result, attackers can execute man-in-the-middle (MITM) attacks to exploit this weakness, potentially enabling them to install malicious packages disguised as legitimate software.
