  "details" : [ "All samba versions 4.9.x before 4.9.18, 4.10.x before 4.10.12 and 4.11.x before 4.11.5 have an issue where if it is set with \"log level = 3\" (or above) then the string obtained from the client, after a failed character conversion, is printed. Such strings can be provided during the NTLMSSP authentication exchange. In the Samba AD DC in particular, this may cause a long-lived process(such as the RPC server) to terminate. (In the file server case, the most likely target, smbd, operates as process-per-client and so a crash there is harmless).", "A flaw was found in samba. When log levels are set at 3 or higher, the string obtained from the client, after a failed character conversion, is printed which could cause long-lived processes to terminate. The highest threat from this vulnerability is to system availability." ],
