Alpine: samba: security update to 4.11.16-r0

medium Tenable Self-Hosted Container Security Plugin ID 407058

Description

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

- A flaw was found in the way samba handled file and directory permissions. An authenticated user could use
this flaw to gain access to certain file and directory information which otherwise would be unavailable to
the attacker. (CVE-2020-14318)

- A null pointer dereference flaw was found in samba's Winbind service in versions before 4.11.15, before
4.12.9 and before 4.13.1. A local user could use this flaw to crash the winbind service causing denial of
service. (CVE-2020-14323)

- A flaw was found in samba's DNS server. An authenticated user could use this flaw to the RPC server to
crash. This RPC server, which also serves protocols other than dnsserver, will be restarted after a short
delay, but it is easy for an authenticated non administrative attacker to crash it again as soon as it
returns. The Samba DNS server itself will continue to operate, but many RPC services will not.
(CVE-2020-14383)
