The (1) Conn_StartLogin and (2) cb_Read_Resolver_Result functions in conn.c
in ngIRCd 18 through 20.2, when the configuration option NoticeAuth is
enabled, does not properly handle the return code for the Handle_Write
function, which allows remote attackers to cause a denial of service
(assertion failure and server crash) via unspecified vectors, related to a
“notice auth” message not being sent to a new client.

seth-arnold | A workaround exists, disable NoticeAuth. Only affects 20, 20.1, and 20.2. |
