CVE-2020-10283 is a critical-severity flaw (CVSS 9.8) affecting micro air vehicle link. Below: why it ranks where it does, which versions are affected, what to do, and the exact commands.

The Micro Air Vehicle Link (MAVLink) protocol presents authentication mechanisms on its version 2.0 however according to its documentation, in order to maintain backwards compatibility, GCS and autopilot negotiate the version via the AUTOPILOT_VERSION message. Since this negotiation depends on the answer, an attacker may craft packages in a way that hints the autopilot to adopt version 1.0 of MAVLink for the communication. Given the lack of authe

Safe to downgrade to: a release before 1.0.0

1. Check installed version

apt-cache policy micro-air-vehicle-link || rpm -q micro-air-vehicle-link || micro-air-vehicle-link --version

2. No fixed release: DOWNGRADE to a release before 1.0.0 (Debian / Ubuntu)

apt-cache madison micro-air-vehicle-link sudo apt install micro-air-vehicle-link=<VERSION_BEFORE_1.0.0> sudo apt-mark hold micro-air-vehicle-link

dnf --showduplicates list micro-air-vehicle-link sudo dnf downgrade micro-air-vehicle-link-<VERSION_BEFORE_1.0.0> sudo dnf versionlock add micro-air-vehicle-link

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
