Affected: 6.58

Fixed in: no fixed release known

Safe to downgrade to: a release before 6.58

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 6.58 (Debian / Ubuntu)

apt-cache madison myproxy sudo apt install myproxy=<VERSION_BEFORE_6.58> sudo apt-mark hold myproxy

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

dnf --showduplicates list myproxy sudo dnf downgrade myproxy-<VERSION_BEFORE_6.58> sudo dnf versionlock add myproxy

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.
