Synopsis
========

Net-SNMP creates temporary files in an insecure manner, possibly
allowing the execution of arbitrary code.

Background
==========

Net-SNMP is a suite of applications used to implement the Simple
Network Management Protocol.

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

    -------------------------------------------------------------------
     Package                /  Vulnerable  /                Unaffected
    -------------------------------------------------------------------
  1  net-analyzer/net-snmp     < 5.2.1-r1                  >= 5.2.1-r1

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

The fixproc application of Net-SNMP creates temporary files with
predictable filenames.

Impact
======

A malicious local attacker could exploit a race condition to change the
content of the temporary files before they are executed by fixproc,
possibly leading to the execution of arbitrary code. A local attacker
could also create symbolic links in the temporary files directory,
pointing to a valid file somewhere on the filesystem. When fixproc is
executed, this would result in the file being overwritten.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Net-SNMP users should upgrade to the latest available version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-analyzer/net-snmp-5.2.1-r1"

Availability
============

This GLSA and any updates to it are available for viewing at
the Gentoo Security Website:
