Timeline

haxx curl UPGRADE
Affected: >= 7.85.0 and < 8.7.0
Fixed in: 8.7.0
Safe to downgrade to: a release before 7.85.0
1. Check installed version
apt-cache policy curl || rpm -q curl || curl --version
2. UPGRADE to 8.7.0 (Debian / Ubuntu)
sudo apt update && sudo apt install --only-upgrade curl
2. UPGRADE (RHEL / Amazon Linux / Fedora)
sudo dnf upgrade curl
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 7.85.0 (Debian / Ubuntu)
apt-cache madison curl sudo apt install curl=<VERSION_BEFORE_7.85.0> sudo apt-mark hold curl
3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)
dnf --showduplicates list curl sudo dnf downgrade curl-<VERSION_BEFORE_7.85.0> sudo dnf versionlock add curl
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.
