SCA: security update for golang.org/x/crypto (GHSA-v778-237x-gjrc)

critical Tenable Self-Hosted Container Security Plugin ID 419150

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

- Applications and libraries which misuse connection.serverAuthenticate (via callback field
ServerConfig.PublicKeyCallback) 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/[email protected] 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)
