Alpine: samba: security update to 4.4.16-r0

high Tenable Cloud Security Plugin ID 407096

Description

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

- It was found that samba before 4.4.16, 4.5.x before 4.5.14, and 4.6.x before 4.6.8 did not enforce "SMB
signing" when certain configuration options were enabled. A remote attacker could launch a man-in-the-
middle attack and retrieve information in plain-text. (CVE-2017-12150)

- A flaw was found in the way samba client before samba 4.4.16, samba 4.5.14 and samba 4.6.8 used encryption
with the max protocol set as SMB3. The connection could lose the requirement for signing and encrypting to
any DFS redirects, allowing an attacker to read or alter the contents of the connection via a man-in-the-
middle attack. (CVE-2017-12151)

- An information leak flaw was found in the way SMB1 protocol was implemented by Samba before 4.4.16, 4.5.x
before 4.5.14, and 4.6.x before 4.6.8. A malicious client could use this flaw to dump server memory
contents to a file on the samba share or to a shared printer, though the exact area of server memory
cannot be controlled by the attacker. (CVE-2017-12163)
