Name of the Vulnerable Software and Affected Versions MIT Kerberos 5 versions prior to 1.10.7 MIT Kerberos 5 versions prior to 1.11.4

Description The issue allows remote attackers to cause a denial of service, potentially leading to a disruption in confidentiality, integrity, and availability of protected information. This can be achieved through crafted requests, specifically targeting the setup server realm function in the Key Distribution Center (KDC) when multiple realms are configured, resulting in a NULL pointer dereference and daemon crash.

Recommendations For versions prior to 1.10.7, update to version 1.10.7 or later to resolve the issue. For versions prior to 1.11.4, update to version 1.11.4 or later to resolve the issue. As a temporary workaround, consider restricting access to the setup server realm function in the KDC to minimize the risk of exploitation.
