Affected: 2.6.0 · 2.6.1 · 2.6.2 · 2.6.3 · 2.6.4 · 2.6.5 · 2.6.6 · 2.6.7

Fixed in: no fixed release known

Safe to downgrade to: a release before 2.6.0

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 2.6.0 (Debian / Ubuntu)

apt-cache madison rsync sudo apt install rsync=<VERSION_BEFORE_2.6.0> sudo apt-mark hold rsync

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

dnf --showduplicates list rsync sudo dnf downgrade rsync-<VERSION_BEFORE_2.6.0> sudo dnf versionlock add rsync

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.
