GLSA 201203-17: HPLIP: Multiple vulnerabilities

http://security.gentoo.org/

Severity:	high
Title:	HPLIP: Multiple vulnerabilities
Date:	03/16/2012
Bugs:	#352085, #388655
ID:	201203-17

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	Architecture(s)
net-print/hplip	< 3.11.10	>= 3.11.10	All supported architectures

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"
