Title: HP Linux Imaging and Printing System 'hplip.postinst' Local Privilege Escalation Vulnerability
Severity: HIGH
Description:
HP Linux Imaging and Printing System (HPLIP) is a Linux-based application to print, scan, and fax with HP inkjet and laser printers.
The application is prone to a local privilege-escalation vulnerability because an installation script changes ownership and permission on certain files in users' home directories. Specifically, 'debian/hplip.postinst' performs actions on users' home directories, including the root user, following an installation or upgrade of HPLIP.
Local attackers can exploit this issue to gain elevated privileges on the affected computer. Successful exploits may completely compromise the computer.

- Hewlett Packard HPLIP 1.6.7
