radare radare2 UPGRADE

Affected: >= 6.1.0 and <= 6.1.6

Fixed in: newer than 6.1.6

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 6.1.0 (Debian / Ubuntu)

apt-cache madison radare2 sudo apt install radare2=<VERSION_BEFORE_6.1.0> sudo apt-mark hold radare2

dnf --showduplicates list radare2 sudo dnf downgrade radare2-<VERSION_BEFORE_6.1.0> sudo dnf versionlock add radare2

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.
