adobe acrobat UPGRADE
Affected: >= 9.0 and < 9.5.4 · >= 10.0 and < 10.1.6 · >= 11.0 and < 11.0.02
Fixed in: 9.5.4, 10.1.6, 11.0.02
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 9.5.4 (Debian / Ubuntu)
sudo apt update && sudo apt install --only-upgrade acrobat
2. UPGRADE (RHEL / Amazon Linux / Fedora)

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

dnf --showduplicates list acrobat
sudo dnf downgrade acrobat-<VERSION_BEFORE_9.0>
