Critical OpenSSH and musl-libc flaws grant unauthorized access to Alpine Linux

By PulseAugur Editorial · [3 sources] ·

A critical vulnerability has been discovered that allows unauthorized access to Alpine Linux and other distributions by exploiting a combination of flaws in OpenSSH and musl-libc. Attackers can gain entry by entering any string longer than 256 characters as a password, bypassing authentication entirely. This issue is particularly concerning for Alpine Linux due to its widespread use in containers and embedded systems, with millions of installations potentially affected. Emergency patches have been released by OpenSSH and musl author Rich Felker, who appear to be attributing fault to each other, while users are urged to apply fixes immediately or disable password authentication. AI

IMPACT This vulnerability highlights the ongoing risks associated with software supply chains and the need for robust security practices in widely deployed systems.

RANK_REASON Security vulnerability affecting widely used Linux distributions and software components.
