Synopsis

The remote Gentoo host is missing one or more security-related patches.

Description

The remote host is affected by the vulnerability described in GLSA-200710-26 (HPLIP: Privilege escalation)

Kees Cook from the Ubuntu Security team discovered that the hpssd daemon does not correctly validate user-supplied data before passing it to a 'popen3()' call. Impact :

A local attacker may be able to exploit this vulnerability by sending a specially crafted request to the hpssd daemon to execute arbitrary commands with the privileges of the user running hpssd, usually root. Workaround :

There is no known workaround at this time.

Solution

All HPLIP users should upgrade to the latest version: # emerge --sync # emerge --ask --oneshot --verbose 'net-print/hplip'
