Timeline

adobe acrobat UPGRADE
Affected: >= 9.0 and < 9.5.5 · >= 10.0 and < 10.1.7 · >= 11.0 and < 11.0.03
Fixed in: 9.5.5, 10.1.7, 11.0.03
Safe to downgrade to: a release before 9.0
1. Check installed version
apt-cache policy acrobat || rpm -q acrobat || acrobat --version
2. UPGRADE to 9.5.5 (Debian / Ubuntu)
sudo apt update && sudo apt install --only-upgrade acrobat
2. UPGRADE (RHEL / Amazon Linux / Fedora)
sudo dnf upgrade acrobat
Note
Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.
3. If no update is available yet, DOWNGRADE to a release before 9.0 (Debian / Ubuntu)
apt-cache madison acrobat sudo apt install acrobat=<VERSION_BEFORE_9.0> sudo apt-mark hold acrobat
3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)
dnf --showduplicates list acrobat sudo dnf downgrade acrobat-<VERSION_BEFORE_9.0> sudo dnf versionlock add acrobat
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.
