Description John Helmert III archtester Gentoo Infrastructure gentoo-dev Security 2023-04-26 02:59:23 UTC 
CVE-2023-30630:

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.

Admittedly needs sudo to get privesc, so down to 2. Patches in 3.5:

https://git.savannah.nongnu.org/cgit/dmidecode.git/commit/?id=6ca381c1247c81f74e1ca4e7706f70bdda72e6f2

Please cleanup <3.5.

Ping. Any reason we need to keep dmidecode 3.4-r1 around?
