If a TLS 1.3 client gets neither a PSK (pre shared key) extension nor a KSE (key share extension) when connecting to a malicious server, a default predictable buffer gets used for the IKM (Input Keying Material) value when generating the session master secret. Using a potentially known IKM value when generating the session master secret key compromises the key generated, allowing an eavesdropper to reconstruct it and potentially allowing access to or meddling with message contents in the session. This issue does not affect client validation of connected servers, nor expose private key information, but could result in an insecure TLS 1.3 session when not controlling both sides of the connection. wolfSSL recommends that TLS 1.3 client side users update the version of wolfSSL used.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

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

  - If a TLS 1.3 client gets neither a PSK (pre shared key) extension nor a KSE (key share extension) when
    connecting to a malicious server, a default predictable buffer gets used for the IKM (Input Keying
    Material) value when generating the session master secret. Using a potentially known IKM value when
    generating the session master secret key compromises the key generated, allowing an eavesdropper to
    reconstruct it and potentially allowing access to or meddling with message contents in the session. This
    issue does not affect client validation of connected servers, nor expose private key information, but
    could result in an insecure TLS 1.3 session when not controlling both sides of the connection. wolfSSL
    recommends that TLS 1.3 client side users update the version of wolfSSL used. (CVE-2023-3724)

The version of mariadb installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2023-3724 advisory.
