Detail
| A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 14.10 - Ubuntu 14.04 LTS - Ubuntu 12.04 LTS Summary: Several security issues were fixed in NTP. Software Description: - ntp: Network Time Protocol daemon and utility programs Details: Miroslav Lichvar discovered that NTP incorrectly validated MAC fields. A remote attacker could possibly use this issue to bypass authentication and spoof packets. (CVE-2015-1798) Miroslav Lichvar discovered that NTP incorrectly handled certain invalid packets. A remote attacker could possibly use this issue to cause a denial of service. (CVE-2015-1799) Juergen Perlinger discovered that NTP incorrectly generated MD5 keys on big-endian platforms. This issue could either cause ntp-keygen to hang, or could result in non-random keys. (CVE number pending) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 14.10: Ubuntu 14.04 LTS: Ubuntu 12.04 LTS: In general, a standard system update will make all the necessary changes.

| Title: | Symmetric-Key feature allows MAC address spoofing. | ||
| Description: | The symmetric-key feature in the receive function in ntp_proto.c in ntpd in NTP 4.x before 4.2.8p2 requires a correct MAC only if the MAC field has a nonzero length, which makes it easier for man-in-the-middle attackers to spoof packets by omitting the MAC. | ||

| Title: | Symmetric-Key feature allows denial of service | ||
| Description: | The symmetric-key feature in the receive function in ntp_proto.c in ntpd in NTP 3.x and 4.x before 4.2.8p2 performs state-variable updates upon receiving certain invalid packets, which makes it easier for man-in-the-middle attackers to cause a denial of service (synchronization loss) by spoofing the source IP address of a peer. | ||
