- Workarounds
- There is no complete mitigation while the serial backend remains installed as a root backend. The following steps reduce risk: 1. If serial printers are not required, remove the serial backend package file or change its permissions so cupsd no longer runs it as root, for example: chmod 0755 /usr/lib/cups/backend/serial (path may be /usr/libexec/cups/backend/serial). 2. Restrict lpadmin (and other SystemGroup) membership to users who are already trusted with root-equivalent access. 3. Leave FileDevice unset or set to No in /etc/cups/cups-files.conf. 4. Keep SELinux in enforcing mode. The cupsd_t domain may block some of the file writes used in this chain.
