Amazon Linux 2 : samba (ALAS-2023-2166)

medium Nessus Plugin ID 178829

Language:

Synopsis

The remote Amazon Linux 2 host is missing a security update.

Description

The version of samba installed on the remote host is prior to 4.10.16-24. It is, therefore, affected by a vulnerability as referenced in the ALAS2-2023-2166 advisory.

 - A flaw was found in Samba. Some SMB1 write requests were not correctly range-checked to ensure the client had sent enough data to fulfill the write, allowing server memory contents to be written into the file (or printer) instead of client-supplied data. The client cannot control the area of the server memory written to the file (or printer). (CVE-2022-32742)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Run 'yum update samba' to update your system.
