The version of runfinch-finch installed on the remote host is prior to 1.6.0-1. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2DOCKER-2025-050 advisory.

    2025-02-12: CVE-2024-51744 was added to this advisory.

    2025-02-12: CVE-2024-45338 was added to this advisory.

    Applications and libraries which misuse the ServerConfig.PublicKeyCallback callback may be susceptible to     an authorization bypass. The documentation for ServerConfig.PublicKeyCallback says that A call to this     function does not guarantee that the key offered is in fact used to authenticate. Specifically, the SSH     protocol allows clients to inquire about whether a public key is acceptable before proving control of the     corresponding private key. PublicKeyCallback may be called with multiple keys, and the order in which the     keys were provided cannot be used to infer which key the client successfully authenticated with, if any.
    Some applications, which store the key(s) passed to PublicKeyCallback (or derived information) and make     security relevant determinations based on it once the connection is established, may make incorrect     assumptions. For example, an attacker may send public keys A and B, and then authenticate with A.
    PublicKeyCallback would be called only twice, first with A and then with B. A vulnerable application may     then make authorization decisions based on key B for which the attacker does not actually control the     private key. Since this API is widely misused, as a partial mitigation golang.org/x/cry...@v0.31.0     enforces the property that, when successfully authenticating via public key, the last key passed to     ServerConfig.PublicKeyCallback will be the key used to authenticate the connection. PublicKeyCallback will     now be called multiple times with the same key, if necessary. Note that the client may still not control     the last key passed to PublicKeyCallback if the connection is then authenticated with a different method,     such as PasswordCallback, KeyboardInteractiveCallback, or NoClientAuth. Users should be using the     Extensions field of the Permissions return value from the various authentication callbacks to record data     associated with the authentication attempt instead of referencing external state. Once the connection is     established the state corresponding to the successful authentication attempt can be retrieved via the     ServerConn.Permissions field. Note that some third-party libraries misuse the Permissions type by sharing     it across authentication attempts; users of third-party libraries should refer to the relevant projects     for guidance. (CVE-2024-45337)

    An attacker can craft an input to the Parse functions that would be processed non-linearly with respect to     its length, resulting in extremely slow parsing. This could cause a denial of service. (CVE-2024-45338)

    golang-jwt is a Go implementation of JSON Web Tokens. Unclear documentation of the error behavior in     `ParseWithClaims` can lead to situation where users are potentially not checking errors in the way they     should be. Especially, if a token is both expired and invalid, the errors returned by `ParseWithClaims`     return both error codes. If users only check for the `jwt.ErrTokenExpired ` using `error.Is`, they will     ignore the embedded `jwt.ErrTokenSignatureInvalid` and thus potentially accept invalid tokens. A fix has     been back-ported with the error handling logic from the `v5` branch to the `v4` branch. In this logic, the     `ParseWithClaims` function will immediately return in dangerous situations (e.g., an invalid signature),     limiting the combined errors only to situations where the signature is valid, but further validation     failed (e.g., if the signature is valid, but is expired AND has the wrong audience). This fix is part of     the 4.5.1 release. We are aware that this changes the behaviour of an established function and is not 100     % backwards compatible, so updating to 4.5.1 might break your code. In case you cannot update to 4.5.0,     please make sure that you are properly checking for all errors (dangerous ones first), so that you are     not running in the case detailed above.
