Synopsis
========
Multiple vulnerabilities have been found in NTP, the worst of which
could result in remote execution of arbitrary code.
Background
==========
NTP is a protocol designed to synchronize the clocks of computers over
a network. The net-misc/ntp package contains the official reference
implementation by the NTP Project.
Affected packages
=================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-misc/ntp < 4.2.8 >= 4.2.8
Description
===========
Multiple vulnerabilities have been discovered in NTP. Please review the
CVE identifiers referenced below for details.
Impact
======
A remote unauthenticated attacker may be able to execute arbitrary code
with the privileges of the process, cause a Denial of Service
condition, and obtain sensitive information that could assist in other
attacks.
Workaround
==========
There is no known workaround at this time.
Resolution
==========
All NTP users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-misc/ntp-4.2.8"
