Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (0.29%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
Description
Actualizer is a single shell script solution to allow developers and embedded engineers to create Debian operating systems (OS). Prior to version 1.2.0, Actualizer uses OpenSSL's "-passwd" function, which uses SHA512 instead of a more suitable password hasher like Yescript/Argon2i. All Actualizer users building a full Debian Operating System are affected. Users should upgrade to version 1.2.0 of Actualizer. Existing OS deployment requires manual password changes against the alpha and root accounts. The change will deploy's Debian's yescript overriding the older SHA512 hash created by OpenSSL. As a workaround, users need to reset both `root` and "Alpha" users' passwords.
