Synopsis

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

2.  Impact Information

Background

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

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.

3.  Resolution Information

Workaround

There is no known workaround at this time.

Resolution

All HPLIP users should upgrade to the latest version:

Code Listing 3.1: Resolution

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