In wolfSSL prior to 5.6.6, if callback functions are enabled (via the WOLFSSL_CALLBACKS flag), then a malicious TLS client or network attacker can trigger a buffer over-read on the heap of 5 bytes (WOLFSSL_CALLBACKS is only intended for debugging).

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

  - In wolfSSL prior to 5.6.6, if callback functions are enabled (via the WOLFSSL_CALLBACKS flag), then a     malicious TLS client or network attacker can trigger a buffer over-read on the heap of 5 bytes     (WOLFSSL_CALLBACKS is only intended for debugging). (CVE-2023-6936)

Note that Nessus relies on the presence of the package as reported by the vendor.

The version of mariadb installed on the remote Azure Linux 3.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2023-6936 advisory.

  - In wolfSSL prior to 5.6.6, if callback functions are enabled (via the WOLFSSL_CALLBACKS flag), then a     malicious TLS client or network attacker can trigger a buffer over-read on the heap of 5 bytes     (WOLFSSL_CALLBACKS is only intended for debugging). (CVE-2023-6936)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

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-2023-6936 advisory.

  - In wolfSSL prior to 5.6.6, if callback functions are enabled (via the WOLFSSL_CALLBACKS flag), then a     malicious TLS client or network attacker can trigger a buffer over-read on the heap of 5 bytes     (WOLFSSL_CALLBACKS is only intended for debugging). (CVE-2023-6936)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.
