CVE-2019-14907
(In the file server case, the most likely target, smbd, operates as process-per-client and so a crash there is harmless).
Does this matter?
Lower severity and a low EPSS score (3.15%). Track it; it rarely justifies an emergency change on its own.
Description
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).
