MiracleLinux 4 : ntp-4.2.6p5-5.0.1.AXS4 (AXSA:2015-327:04)
high Nessus Plugin ID 289008
Synopsis
The remote MiracleLinux host is missing one or more security updates.Description
The remote MiracleLinux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2015-327:04 advisory.The Network Time Protocol (NTP) is used to synchronize a computer's time with another reference time source. This package includes ntpd (a daemon which continuously adjusts system time) and utilities used to query and configure the ntpd daemon.
Perl scripts ntp-wait and ntptrace are in the ntp-perl package and the ntpdate program is in the ntpdate package. The documentation is in the ntp-doc package.
Security issues fixed with this release:
CVE-2014-9297 CVE-2014-9298 CVE-2015-1798 CVE-2015-1799 CVE-2015-3405 Fixed bugs:
* The ntpd daemon truncated symmetric keys specified in the key file to 20 bytes. As a consequence, it was impossible to configure NTP authentication to work with peers that use longer keys. To fix this bug, the maximum length of keys has now been changed to 32 bytes.
* The ntp-keygen utility used the exponent of 3 when generating RSA keys, and generating RSA keys failed when FIPS mode was enabled. ntp-keygen has been modified to use the exponent of 65537, and generating keys in FIPS mode now works as expected.
* The ntpd daemon included a root delay when calculating its root dispersion.
Consequently, the NTP server reported larger root dispersion than it should have and clients could reject the source when its distance reached the maximum synchronization distance (1.5 seconds by default). Calculation of root dispersion has been fixed, the root dispersion is now reported correctly, and clients no longer reject the server due to a large synchronization distance.
* The ntpd daemon dropped incoming NTP packets if their source port was lower than 123 (the NTP port). Clients behind Network Address Translation (NAT) were unable to synchronize with the server if their source port was translated to ports below 123. With this update, the bug was fixed.
Enhancements:
* This update introduces configurable access of memory segments used for Shared Memory Driver (SHM) reference clocks. Previously, only the first two memory segments were created with owner-only access, allowing just two SHM reference clocks to be used securely on a system. Now, the owner-only access to SHM is configurable with the mode option, and it is therefore possible to use more SHM reference clocks securely.
* Support for nanosecond resolution has been added to the SHM reference clock.
Prior to this update, when a Precision Time Protocol (PTP) hardware clock was used as a time source to synchronize the system clock (for example, with the timemaster service from the linuxptp package), the accuracy of the synchronization was limited due to the microsecond resolution of the SHM protocol. The nanosecond extension in the SHM protocol now enables sub-microsecond synchronization of the system clock.
Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.
Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
