  "title": "ctdb: A flaw was found in Samba",
  "description": "A flaw was found in Samba. It is susceptible to a vulnerability where multiple incompatible RPC listeners can be initiated, causing disruptions in the AD DC service. When Samba\u0027s RPC server experiences a high load or unresponsiveness, servers intended for non-AD DC purposes (for example, NT4-emulation \u0022classic DCs\u0022) can erroneously start and compete for the same unix domain sockets. This issue leads to partial query responses from the AD DC, causing issues such as \u0022The procedure number is out of range\u0022 when using tools like Active Directory Users. This flaw allows an attacker to disrupt AD DC services.",
