ALAS-2020-1452


Amazon Linux AMI Security Advisory: ALAS-2020-1452
Advisory Release Date: 2020-11-14 01:23 Pacific
Advisory Updated Date: 2020-11-16 20:48 Pacific
Severity: Medium
References: CVE-2019-14907 

Issue Overview:

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). (CVE-2019-14907 )
