HP Linux Imaging and Printing (HPLIP) before 3.13.2 uses world-writable permissions for /var/log/hp and /var/log/hp/tmp, which allows local users to delete log files via standard filesystem operations.

Sebastian Krahmer reported a security issue was found in polkit (CVE-2013-4288 bz 1002375).

It was found that hplip was vulnerable to this issue as well, since it communicated to polkit authority using an unsafe DBUS interface.

This issue has been assigned CVE-2013-4325
