Synopsis
========

A vulnerability has been discovered in sudo which could result in denial
of service.

Background
==========

sudo allows a system administrator to give users the ability to run
commands as other users.

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

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  app-admin/sudo             < 1.9.12-r1              >= 1.9.12-r1

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

In certain password input handling, sudo incorrectly assumes the
password input is at least nine bytes in size, leading to a heap buffer
overread.

Impact
======

In the worst case, the heap buffer overread can result in the denial of
service of the sudo process.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All sudo users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=app-admin/sudo-1.9.12-r1"
