emerson rosemount transmitter interface software MITIGATE
Affected: all versions
Fixed in: no fixed release known
Safe to downgrade to: no unaffected older release
1. Check installed version
apt-cache policy rosemount-transmitter-interface-software || rpm -q rosemount-transmitter-interface-software || rosemount-transmitter-interface-software --version
No fixed or unaffected release known
Apply the vendor mitigation from the advisory, disable the affected feature, or restrict network access.
pepperl-fuchs pactware UPGRADE
Affected: >= 5.0 and <= 5.0.5.31
Fixed in: newer than 5.0.5.31
Safe to downgrade to: a release before 5.0
1. Check installed version
apt-cache policy pactware || rpm -q pactware || pactware --version
2. UPGRADE to newer than 5.0.5.31 (Debian / Ubuntu)
sudo apt update && sudo apt install --only-upgrade pactware
2. UPGRADE (RHEL / Amazon Linux / Fedora)
sudo dnf upgrade pactware
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 5.0 (Debian / Ubuntu)
apt-cache madison pactware
sudo apt install pactware=<VERSION_BEFORE_5.0>
sudo apt-mark hold pactware
3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)
dnf --showduplicates list pactware
sudo dnf downgrade pactware-<VERSION_BEFORE_5.0>
