Synopsis
========

Gentoo's collectd package contains multiple vulnerabilities, the worst
of which may allow local attackers to escalate privileges.

Background
==========

collectd is a daemon which collects system and application performance
metrics periodically and provides mechanisms to store the values in a
variety of ways, for example in RRD files.

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

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  app-admin/collectd          < 5.7.2-r1               >= 5.7.2-r1 

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

Multiple vulnerabilities have been found in Gentoo's collectd package.
Please review the referenced CVE identifiers and bug entries for
details.

Impact
======

A local attacker, who either is already collectd's system user or
belongs to collectd's group, could potentially gain root privileges and
cause a Denial of Service condition.

Remote attackers could cause a Denial of Service condition via
specially crafted SNMP responses.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All collectd users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot --verbose ">=app-admin/collectd-5.7.2-r1"
