This signature detects attempts to exploit a known vulnerability in Multiple Vendors NTP Daemon. A successful attack can lead to a buffer overflow and arbitrary remote code execution within the context of the server.
The 'ntpd' daemon is prone to a stack-based buffer-overflow vulnerability when it is configured to use the 'autokey' OpenSSL protocol. Attackers can exploit this issue to execute arbitrary code in the context of the application. Failed attempts will likely crash the application, causing denial-of-service conditions.
