Multiple Vulnerabilities in ntpd Affecting Cisco Products - October 2015
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 create a denial of service (DoS) condition or modify the time being advertised by a device acting as a network time protocol (NTP) server.
On October 21st, 2015, NTP.org released a security advisory detailing 13 issues regarding multiple DoS vulnerabilities, information disclosure vulnerabilities, and logic issues that may result in an attacker gaining the ability to modify an NTP server's advertised time. The vulnerabilities covered in this document are as follows:

CVE-2015-7701 [HIGH] CWE-401 ntp: slow memory leak in CRYPTO_ASSOC
ntp: slow memory leak in CRYPTO_ASSOC
Memory leak in the CRYPTO_ASSOC function in ntpd in NTP 4.2.x before 4.2.8p4, and 4.3.x before 4.3.77 allows remote attackers to cause a denial of service (memory consumption).
A memory leak flaw was found in ntpd's CRYPTO_ASSOC. If ntpd was configured to use autokey authentication, an attacker could send packets to ntpd that would, after several days of ongoing attack, cause it to run out of memory.
Mitigation: Disable NTP autokey authentication by removing, or commenting out, all configuration directives beginning with the 'crypto' keyword in your ntp.conf file.

A memory leak flaw was found in ntpd's CRYPTO_ASSOC. If ntpd is configured to use autokey authentication, an attacker could send packets to ntpd that would, after several days of ongoing attack, cause it to run out of memory.
Mitigation:
Disable NTP autokey authentication by removing, or commenting out, all configuration directives beginning with the 'crypto' keyword in your ntp.conf file.
