Description détaillée

A privilege escalation vulnerability was found in CUPS when used with the cups-filters serial backend. A local user who is a member of the lpadmin group can configure a printer that uses a privileged serial backend. The CUPS scheduler does not restrict the path component of non-file device URIs, so the root-privileged backend can write attacker-controlled print data to an arbitrary file. This can be used to change security-sensitive CUPS configuration and ultimately achieve root code execution. Exploitation requires local lpadmin group membership and a serial backend binary installed with root-only permissions.
