Detail
| Multiple vulnerabilities were discovered in ntp, an implementation of the Network Time Protocol: CVE-2015-1798 When configured to use a symmetric key with an NTP peer, ntpd would accept packets without MAC as if they had a valid MAC. This could allow a remote attacker to bypass the packet authentication and send malicious packets without having to know the symmetric key. CVE-2015-1799 When peering with other NTP hosts using authenticated symmetric association, ntpd would update its internal state variables before the MAC of the NTP messages was validated. This could allow a remote attacker to cause a denial of service by impeding synchronization between NTP peers. Additionally, it was discovered that generating MD5 keys using ntp-keygen on big endian machines would either trigger an endless loop, or generate non-random keys. For the stable distribution (wheezy), these problems have been fixed in version 1:4.2.6.p5+dfsg-2+deb7u4. For the unstable distribution (sid), these problems have been fixed in version 1:4.2.6.p5+dfsg-7. We recommend that you upgrade your ntp packages. |

| 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. | ||
