Echo: samba: security update to 2:4.11.5+dfsg-1

medium Tenable Cloud Security Plugin ID 460341

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - 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)

Solution

Update the samba library and its related packages to version 2:4.11.5+dfsg-1 or later.
