medium Nessus Plugin ID 179328

Synopsis

The remote AlmaLinux host is missing a security update.

Description

The remote AlmaLinux 8 host has packages installed that are affected by a vulnerability as referenced in the ALSA-2023:4328 advisory.

 - A vulnerability was found in Samba's SMB2 packet signing mechanism. The SMB2 packet signing is not enforced if an admin configured server signing = required or for SMB2 connections to Domain Controllers where SMB2 packet signing is mandatory. This flaw allows an attacker to perform attacks, such as a man-in- the-middle attack, by intercepting the network traffic and modifying the SMB2 messages between client and server, affecting the integrity of the data. (CVE-2023-3347)

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

Solution

Update the affected packages.
