Name of the Vulnerable Software and Affected Versions NTP versions prior to 4.2.8p9

Description The issue allows remote attackers to set or unset traps via a crafted control mode packet, which can lead to a denial of service caused by a NULL pointer dereference when the trap service has been enabled. By sending specially crafted packets, a remote attacker could exploit this to cause the application to crash.

Recommendations For versions prior to 4.2.8p9, update to version 4.2.8p9 or later to resolve the issue. As a temporary workaround, consider disabling the trap service to minimize the risk of exploitation. Restrict access to the control mode functionality to minimize the risk of exploitation.
