Synopsis
========

A vulnerability has been discovered in Dmidecode, which can lead to
privilege escalation.

Background
==========

Dmidecode reports information about your system's hardware as described
in your system BIOS according to the SMBIOS/DMI standard (see a sample
output). This information typically includes system manufacturer, model
name, serial number, BIOS version, asset tag as well as a lot of other
details of varying level of interest and reliability depending on the
manufacturer. This will often include usage status for the CPU sockets,
expansion slots (e.g. AGP, PCI, ISA) and memory module slots, and the
list of I/O ports (e.g. serial, parallel, USB).

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

Package             Vulnerable    Unaffected
------------------  ------------  ------------
sys-apps/dmidecode  < 3.5         >= 3.5

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

Dmidecode -dump-bin can overwrite a local file. This has security
relevance because, for example, execution of Dmidecode via sudo is
plausible.

Impact
======

Please review the referenced CVE identifier for details.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Dmidecode users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=sys-apps/dmidecode-3.5"
