New! Plugin Severity Now Using CVSS v3

Synopsis

The remote Debian host is missing a security update.

Description

Several vulnerabilities were discovered in the ntp package, an implementation of the Network Time Protocol. The Common Vulnerabilities and Exposures project identifies the following problems :

CVE-2014-9297

Stephen Roettger of the Google Security Team, Sebastian Krahmer of the SUSE Security Team and Harlan Stenn of Network Time Foundation discovered that the length value in extension fields is not properly validated in several code paths in ntp_crypto.c, which could lead to information leakage or denial of service (ntpd crash).

CVE-2014-9298

Stephen Roettger of the Google Security Team reported that ACLs based on IPv6 ::1 addresses can be bypassed.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected ntp, ntp-doc, and ntpdate packages.
