CZ Urges Alpine Linux Users to Patch a Decade-Old OpenSSH Flaw

CZ urged users of some Alpine Linux configurations to patch a password-bypass flaw in OpenSSH, warning that it has remained in the software for about 10 years.

CZ's social media warning identifies OpenSSH and Alpine Linux as the software and environment involved. It describes the issue as a password bypass affecting some configurations. The post calls on users who have not yet fixed the problem to apply a repair patch.

The decade-long lifespan is the key detail in the warning: CZ characterized the issue as having persisted for roughly 10 years. The request is aimed at users who have not handled the problem, with prompt patching as the next step. The warning focuses on Alpine Linux configurations and does not say that every OpenSSH installation is affected. Its repair guidance is conditional: patch the issue if it has not already been addressed.
