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)

Tenable has extracted the preceding description block directly from the tested product security advisory.

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.
