newatlanta servletexec DOWNGRADE

Affected: 2.2 · 3.0

Fixed in: no fixed release known

Safe to downgrade to: a release before 2.2

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 2.2 (Debian / Ubuntu)

apt-cache madison servletexec sudo apt install servletexec=<VERSION_BEFORE_2.2> sudo apt-mark hold servletexec

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

dnf --showduplicates list servletexec sudo dnf downgrade servletexec-<VERSION_BEFORE_2.2> sudo dnf versionlock add servletexec

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.
