bloodshed dev-c\+\+ DOWNGRADE

Affected: 4.9.9.2

Fixed in: no fixed release known

Safe to downgrade to: a release before 4.9.9.2

1. Check installed version

apt-cache policy dev-c++ || rpm -q dev-c++ || dev-c++ --version

2. No fixed release: DOWNGRADE to a release before 4.9.9.2 (Debian / Ubuntu)

apt-cache madison dev-c++ sudo apt install dev-c++=<VERSION_BEFORE_4.9.9.2> sudo apt-mark hold dev-c++

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

dnf --showduplicates list dev-c++ sudo dnf downgrade dev-c++-<VERSION_BEFORE_4.9.9.2> sudo dnf versionlock add dev-c++

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.
