A remote\nattacker could possibly use this issue to brute force the authentication\nkey and send requests if permitted by IP restrictions.

(CVE-2014-9294)\n\nStephen Roettger discovered that NTP contained buffer overflows in the\ncrypto_recv(), ctl_putdata() and configure() functions. In non-default\nconfigurations, a remote attacker could use these issues to cause NTP to\ncrash, resulting in a denial of service, or possibly execute arbitrary\ncode. The default compiler options for affected releases should reduce the\nvulnerability to a denial of service. In addition, attackers would be\nisolated by the NTP AppArmor profile.
