Synopsis
========

Multiple vulnerabilities have been found in HPLIP, the worst of which
may allow execution of arbitrary code.

Background
==========

The Hewlett-Packard Linux Imaging and Printing system (HPLIP) provides
drivers for HP's inkjet and laser printers, scanners and fax machines.

Affected packages
=================

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  net-print/hplip             < 3.11.10                 >= 3.11.10

Description
===========

Two vulnerabilities have been found in HPLIP:

* The "hpmud_get_pml()" function in pml.c contains a boundary error
  which could cause a stack-based buffer overflow (CVE-2010-4267).
* The "send_data_to_stdout()" function in hpcupsfax.cpp creates
  insecure temporary files (CVE-2011-2722).

Impact
======

A remote attacker might send specially crafted SNMP reponses, possibly
resulting in execution of arbitrary code or a Denial of Service
condition. Furthermore, a local attacker could perform symlink attacks
to overwrite arbitrary files.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All HPLIP users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=net-print/hplip-3.11.10"
