Overview
Affected versions of this package are vulnerable to Improper Validation of Array Index via the cups web ui when a user in the lpadmin group changes the configuration and inserts a malicious line. An attacker can trigger a stack-based out-of-bounds write by submitting a specially crafted configuration, which is then parsed by the cupsd process running as root.
Note: This is only exploitable if the attacker has lpadmin group privileges and access to the web interface.
