tinyhttpd tinyhttpd DOWNGRADE

Affected: 0.1.0

Fixed in: no fixed release known

Safe to downgrade to: a release before 0.1.0

1. Check installed version

apt-cache policy tinyhttpd || rpm -q tinyhttpd || tinyhttpd --version

2. No fixed release: DOWNGRADE to a release before 0.1.0 (Debian / Ubuntu)

apt-cache madison tinyhttpd sudo apt install tinyhttpd=<VERSION_BEFORE_0.1.0> sudo apt-mark hold tinyhttpd

dnf --showduplicates list tinyhttpd sudo dnf downgrade tinyhttpd-<VERSION_BEFORE_0.1.0> sudo dnf versionlock add tinyhttpd

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.
