CVE-2011-1829: APT before 0.8.15.2 does not properly validate inline GPG signatures, which allows man-in-the-middle attack...

Security readout for executives and security teams

This flaw affects older APT package-management behavior. If an attacker can intercept package traffic, APT may accept modified package data because inline GPG signatures are not properly validated. That can turn routine software updates into a path for installing attacker-modified packages. Exposure is most likely on Debian or Ubuntu-derived systems using APT versions before 0.8.15.2. Risk is highest where package retrieval crosses untrusted or interceptable networks. The source bundle does not enumerate exact affected distributions or supported package names beyond APT. Treat this as a high-priority legacy package-management risk where old Debian or Ubuntu systems remain in service. It can undermine software supply-chain trust, but urgency is lower for patched or currently supported systems. Mitigation focus: Upgrade APT to 0.8.15.2 or a vendor-provided fixed package.; Apply relevant Debian or Ubuntu security updates where applicable.; Prioritize systems that retrieve packages across untrusted networks..
