LIN1019-3963 : Security Advisory - samba - CVE-2019-14907

Created: Jan 22, 2020    Updated: May 13, 2022
Resolved Date: Feb 2, 2020
Found In Version: 10.19.45.1
Fix Version: 10.19.45.4
Severity: Standard
Applicable for: Wind River Linux LTS 19
Component/s: Userspace

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).
