CVE-2016-1252: The apt package in Debian jessie before 1.0.9.8.4, in Debian unstable before 1.4~beta2, in Ubuntu 14.04 LTS...

The apt package in Debian jessie before 1.0.9.8.4, in Debian unstable before 1.4~beta2, in Ubuntu 14.04 LTS before 1.0.1ubuntu2.17, in Ubuntu 16.04 LTS before 1.2.15ubuntu0.2, and in Ubuntu 16.10 before 1.3.2ubuntu0.1 allows man-in-the-middle attackers to bypass a repository-signing protection mechanism by leveraging improper error handling when validating InRelease file signatures.

Security readout for executives and security teams

This flaw affects apt, the package manager used by Debian and Ubuntu. A network attacker positioned between a system and its software repository could bypass repository signature protection during InRelease validation. That could undermine trust in system updates on affected releases, making patching and legacy-host review important. Exposure is mainly older Debian jessie and Ubuntu 14.04, 16.04, or 16.10 systems that still use vulnerable apt versions. Internet-facing status is less relevant than whether package updates traverse attacker-influenced networks, proxies, mirrors, or untrusted paths. Prioritize remediation for legacy Debian and Ubuntu systems still receiving updates through vulnerable apt. The business risk is supply-chain compromise of system updates, especially in environments with old base images, unmanaged servers, or weak network trust boundaries. Mitigation focus: Upgrade apt to the fixed Debian or Ubuntu versions named by vendor advisories.; Replace end-of-life Debian or Ubuntu releases with supported operating system versions.; Review Debian DSA-3733 and Ubuntu USN-3156-1 for vendor-specific remediation details..
