Alpine: samba: security update to 4.10.12-r0

medium Tenable Self-Hosted Container Security Plugin ID 407050

Description

There are packages installed that are affected by multiple vulnerabilities referenced in the following CVEs:

- There is an issue in all samba 4.11.x versions before 4.11.5, all samba 4.10.x versions before 4.10.12 and
all samba 4.9.x versions before 4.9.18, where the removal of the right to create or modify a subtree would
not automatically be taken away on all domain controllers. (CVE-2019-14902)

- 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)

- There is a use-after-free issue in all samba 4.9.x versions before 4.9.18, all samba 4.10.x versions
before 4.10.12 and all samba 4.11.x versions before 4.11.5, essentially due to a call to realloc() while
other local variables still point at the original buffer. (CVE-2019-19344)
