Gentoo Linux Security Advisory

Title: HPLIP: Multiple vulnerabilities (GLSA 201203-17)
Severity: high
Exploitable: local, remote
Date: March 16, 2012
Bug(s): #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: net-print/hplip
Vulnerable: < 3.11.10
Unaffected: >= 3.11.10
Architectures: 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:
Code:
# emerge --sync
      # emerge --ask --oneshot --verbose ">=net-print/hplip-3.11.10"
