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"
