Echo: samba: security update to 2:4.16.0+dfsg-2

high Tenable Self-Hosted Container Security Plugin ID 459114

Description

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

 - The Samba vfs_fruit module uses extended file attributes (EA, xattr) to provide "...enhanced compatibility
 with Apple SMB clients and interoperability with a Netatalk 3 AFP fileserver." Samba versions prior to
 4.13.17, 4.14.12 and 4.15.5 with vfs_fruit configured allow out-of-bounds heap read and write via
 specially crafted extended file attributes. A remote attacker with write access to extended file
 attributes can execute arbitrary code with the privileges of smbd, typically root. (CVE-2021-44142)

Solution

Update the samba library and its related packages to version 2:4.16.0+dfsg-2 or later.
