A vulnerability has been identified in HP Linux Imaging and Printing System (HPLIP), which could be exploited by local attackers to obtain elevated privileges. This issue is caused by input validation errors in the hpssd daemon that does not validate user-supplied data before being passed to a "popen3()" call, which could be exploited by malicious users to inject and execute arbitrary commands with "root" privileges.
