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.

mdeslaur | This CVE relies on an improbable non-default configuration of allowing an unprivileged user to run demidecode under sudo with a specific insecure configuration in the sudoers file. Using dmidecode in such a manner is no different than allowing any other tool to unexpectedly run with elevated privileges. Setting priority to low. The upstream commits listed below only prevent overwriting a file as root, but still allows creating arbitrary files as root so using dmidecode with elevated privileges via sudoers is still unsafe. |
