Affected: 1.2.4

Fixed in: no fixed release known

Safe to downgrade to: a release before 1.2.4

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 1.2.4 (Debian / Ubuntu)

apt-cache madison evolution sudo apt install evolution=<VERSION_BEFORE_1.2.4> sudo apt-mark hold evolution

2. No fixed release: DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list evolution sudo dnf downgrade evolution-<VERSION_BEFORE_1.2.4> sudo dnf versionlock add evolution

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.
