oss-sec alert: question about password authentication bypass in OpenSSH with musl libc
A November 5, 2026 post on the oss-sec list asks whether an error string with a colon would keep the value from being treated as field content in the OpenSSH password flow with musl libc.
What the source says: a post on the oss-sec discussion list, dated November 5, 2026, titled “sshole”: password authentication bypass in OpenSSH + musl libc. The available text is a short machine translation. It raises a design question: if an error message is emitted, would using “:” or “::” better express the intent of never seeing that content as a field, since the colon is a field separator.
What the material does not include: the excerpt does not describe affected versions, vulnerability identifiers, reproduction steps, a fix, or measured impact. The title mentions password authentication bypass, but the body does not confirm technical details. So do not treat this summary as a failure analysis or a fix recommendation.
Relevance to your organization: the case shows that error messages and separator-based fields can be interpreted differently by different components. To verify, search the public oss-sec archive by title and date, and check the official advisories from the OpenSSH and musl libc maintainers. Rota Nacional does not fix or assess this flaw.
