This element in the array, and the content it describes are not included in the signature verification. The content describes one or more WIN_CERTIFICATES that are used in signature verification.\nFor obvious reasons the content itself cannot be part of the signature check (else by calculating it, it would change the signature itself). However, the DataDirectory entry itself, could be part of the signature check. It is currently not the case.\nBecause it's not, it gives an attacker a lot of leaway to take an existing validly signed .efi, make the room for the EFI_IMAGE_DIRECTORY_ENTRY_SECURITY content larger, and start adding content to it, while still leaving the WIN_CERTIFICATE in tact enough to pass signature verification. This would allow an attacker to get arbitrary content inside of the the EFI_IMAGE_DIRECTORY_ENTRY_SECURITY content mapped into memory, presumably with RWX or RX page protections. Hence having shellcode ready to go, in case an exploit is found somewhere (bypassing exploit mitigations)."], "name": "CVE-2019-14576", "package_state": [{"cpe": "cpe:/o:redhat:enterprise_linux:7", "fix_state": "Not affected", "package_name": "ovmf", "product_name": "Red Hat Enterprise Linux 7"}, {"cpe": "cpe:/o:redhat:enterprise_linux:8", "fix_state": "Not affected", "package_name": "edk2", "product_name": "Red Hat Enterprise Linux 8"}], "public_date": "2023-03-01T00:00:00Z", "references": ["https://www.cve.org/CVERecord?id=CVE-2019-14576\nhttps://nvd.nist.gov/vuln/detail/CVE-2019-14576"], "statement": "This CVE has been rejected as it does not consider this to be a security vulnerability, given that to exploit this you need another existing vulnerability. This is more of a second security layer/hardening feature.\nRed Hat has evaluated this issue and determined that it does not meet the criteria to be classified as a security vulnerability. This assessment is based on the issue not posing a significant security risk, being a result of misconfiguration or usage error, or falling outside the scope of security considerations. \nAs such, this CVE has been marked as \"Rejected\" in alignment with Red Hat's vulnerability management policies.\nIf you have additional information or concerns regarding this determination, please contact Red Hat Product Security for further clarification."}
