Updated ntp packages fix security vulnerabilities

Updated ntp packages fix security vulnerabilities: The symmetric-key feature in the receive function in ntpproto.c in ntpd in NTP 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 th...

Multiple Vulnerabilities in ntpd (April 2015) Affecting Cisco Products

Multiple Cisco products incorporate a version of the ntpd package. Versions of this package are affected by one or more vulnerabilities that could allow an unauthenticated, remote attacker to bypass authentication controls or to create a denial of service DoS condition. On April 7, 2015, NTP.org...

CVE-2015-1799

The symmetric-key feature in the receive function in ntpproto.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...

CVE-2015-1799

The CVE-2015-1799 issue affects ntpd's handling of symmetric-key authenticated peering. The vulnerability arises because ntpd may update internal state variables (state-variable updates) when processing certain invalid packets, which could allow a remote attacker—likely on the same or neighboring...
