CBL Mariner 2.0 Security Update: edk2 / hvloader / openssl / nodejs18 (CVE-2023-0464)

high Nessus Plugin ID 183087


The remote CBL Mariner host is missing one or more security updates.


The version of edk2 / hvloader / openssl / nodejs18 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-2023-0464 advisory.

- A security vulnerability has been identified in all supported versions of OpenSSL related to the verification of X.509 certificate chains that include policy constraints. Attackers May be able to exploit this vulnerability by creating a malicious certificate chain that triggers exponential use of computational resources, leading to a denial-of-service (DoS) attack on affected systems. Policy processing is disabled by default but can be enabled by passing the `-policy' argument to the command line utilities or by calling the `X509_VERIFY_PARAM_set1_policies()' function. (CVE-2023-0464)

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


Update the affected packages.
