Affected: 0.8 · 0.8.13 · 0.8.14 · 0.8.15 · 0.8.18 · 0.8.19 · 0.9 · 0.9.1

Fixed in: no fixed release known

Safe to downgrade to: a release before 0.8

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 0.8 (Debian / Ubuntu)

apt-cache madison ethereal sudo apt install ethereal=<VERSION_BEFORE_0.8> sudo apt-mark hold ethereal

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

dnf --showduplicates list ethereal sudo dnf downgrade ethereal-<VERSION_BEFORE_0.8> sudo dnf versionlock add ethereal

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.
