Date:	07/24/2024
Bugs:	#905093
ID:	202407-26

Synopsis

A vulnerability has been discovered in Dmidecode, which can lead to privilege escalation.

Background

Dmidecode reports information about your system's hardware as described in your system BIOS according to the SMBIOS/DMI standard (see a sample output). This information typically includes system manufacturer, model name, serial number, BIOS version, asset tag as well as a lot of other details of varying level of interest and reliability depending on the manufacturer. This will often include usage status for the CPU sockets, expansion slots (e.g. AGP, PCI, ISA) and memory module slots, and the list of I/O ports (e.g. serial, parallel, USB).

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
sys-apps/dmidecode	< 3.5	>= 3.5	All supported architectures

Description

Dmidecode -dump-bin can overwrite a local file. This has security relevance because, for example, execution of Dmidecode via sudo is plausible.

Impact

Please review the referenced CVE identifier for details.

Workaround

There is no known workaround at this time.

Resolution

All Dmidecode users should upgrade to the latest version:

          # emerge --sync
          # emerge --ask --oneshot --verbose ">=sys-apps/dmidecode-3.5"
