========================================================================== Ubuntu Security Notice USN-2497-1 February 09, 2015
ntp vulnerabilities ==========================================================================
A security issue affects these releases of Ubuntu and its derivatives:
- Ubuntu 14.10 - Ubuntu 14.04 LTS - Ubuntu 12.04 LTS - Ubuntu 10.04 LTS
Summary:
Several security issues were fixed in NTP.
Software Description: - ntp: Network Time Protocol daemon and utility programs
Details:
Stephen Roettger, Sebastian Krahmer, and Harlan Stenn discovered that NTP incorrectly handled the length value in extension fields. A remote attacker could use this issue to possibly obtain leaked information, or cause the NTP daemon to crash, resulting in a denial of service. (CVE-2014-9297)
Stephen Roettger discovered that NTP incorrectly handled ACLs based on certain IPv6 addresses. (CVE-2014-9298)
Update instructions:
The problem can be corrected by updating your system to the following package versions:
Ubuntu 14.10: ntp 1:4.2.6.p5+dfsg-3ubuntu2.14.10.2
Ubuntu 14.04 LTS: ntp 1:4.2.6.p5+dfsg-3ubuntu2.14.04.2
Ubuntu 12.04 LTS: ntp 1:4.2.6.p3+dfsg-1ubuntu3.3
Ubuntu 10.04 LTS: ntp 1:4.2.4p8+dfsg-1ubuntu2.3
In general, a standard system update will make all the necessary changes.
