Affected: < 3.6.13 · >= 3.7.0 and < 3.7.10 · >= 3.8.0 and < 3.8.7 · >= 3.9.0 and < 3.9.1

Fixed in: 3.6.13, 3.7.10, 3.8.7, 3.9.1

Safe to downgrade to: a release before 3.7.0

1. Check installed version

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

2. UPGRADE to 3.6.13 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade python

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade python

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 3.7.0 (Debian / Ubuntu)

apt-cache madison python sudo apt install python=<VERSION_BEFORE_3.7.0> sudo apt-mark hold python

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list python sudo dnf downgrade python-<VERSION_BEFORE_3.7.0> sudo dnf versionlock add python

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.
