Multiple Vulnerabilities in Network Time Protocol Daemon Affecting Cisco Products: April 2016
Multiple Cisco products incorporate a version of the Network Time Protocol daemon (ntpd) package. Versions of this package are affected by one or more vulnerabilities that could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition or modify the time being advertised by a device acting as a Network Time Protocol (NTP) server.
On April 26, 2016, the NTP Consortium of the Network Time Foundation released a security notice that details 11 issues regarding DoS vulnerabilities, information disclosure vulnerabilities, and logic issues that may allow an attacker to shift a system's time. Two of the vulnerabilities disclosed in the NTP security notice address issues that

CVE-2016-2518 [MEDIUM] ntp: out-of-bounds references on crafted packet
ntp: out-of-bounds references on crafted packet
The MATCH_ASSOC function in NTP before version 4.2.8p9 and 4.3.x before 4.3.92 allows remote attackers to cause an out-of-bounds reference via an addpeer request with a large hmode value.
An out-of-bounds access flaw was found in the way ntpd processed certain packets. An authenticated attacker could use a crafted packet to create a peer association with hmode of 7 and larger, which could potentially (although highly unlikely) cause ntpd to crash.
