  "description": "Initial UEFI bootloader that handles chaining to a trusted full \\ bootloader under secure boot environments.\r\n\r\nSecurity Fix(es):\r\n\r\nA security vulnerability has been identified in all supported versions\r\n\r\nof OpenSSL related to the verification of X.509 certificate chains\nthat include policy constraints.  Attackers may be able to exploit this\nvulnerability by creating a malicious certificate chain that triggers\nexponential use of computational resources, leading to a denial-of-service\n(DoS) attack on affected systems.\r\n\r\nPolicy processing is disabled by default but can be enabled by passing\nthe `-policy' argument to the command line utilities or by calling the\n`X509_VERIFY_PARAM_set1_policies()' function.(CVE-2023-0464)",
