Echo: dmidecode: security update to 3.6

high Tenable Cloud Security Plugin ID 464924

Description

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

 - Dmidecode before 3.5 allows -dump-bin to overwrite a local file. This has security relevance because, for
 example, execution of Dmidecode via Sudo is plausible. NOTE: Some third parties have indicated the fix in
 3.5 does not adequately address the vulnerability. The argument is that the proposed patch prevents
 dmidecode from writing to an existing file. However, there are multiple attack vectors that would not
 require overwriting an existing file that would provide the same level of unauthorized privilege
 escalation (e.g. creating a new file in /etc/cron.hourly). (CVE-2023-30630)

Solution

Update the dmidecode library and its related packages to version 3.6 or later.
