genivia gsoap DOWNGRADE

Affected: 2.8.0

Fixed in: no fixed release known

Safe to downgrade to: a release before 2.8.0

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 2.8.0 (Debian / Ubuntu)

apt-cache madison gsoap sudo apt install gsoap=<VERSION_BEFORE_2.8.0> sudo apt-mark hold gsoap

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

dnf --showduplicates list gsoap sudo dnf downgrade gsoap-<VERSION_BEFORE_2.8.0> sudo dnf versionlock add gsoap

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.
