REF:https://bugzilla.tianocore.org/show_bug.cgi?id=4542 Bug Overview: PixieFail Bug #9 CVE-2023-45237 CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N CWE-338 Use of Cryptographically Weak Pseudo-Random Number Generator (PRNG) Use of a Weak PseudoRandom Number Generator Change Overview: Updates all Instances of NET_RANDOM (NetRandomInitSeed ()) to either > > EFI_STATUS > EFIAPI > PseudoRandomU32 ( > OUT UINT32 *Output > ); > or (depending on the use case) > > EFI_STATUS > EFIAPI > PseudoRandom ( > OUT VOID *Output, > IN UINTN OutputLength > ); > This is because the use of Example: The following code snippet PseudoRandomU32 () function is used: > > UINT32 Random; > > Status = PseudoRandomU32 (&Random); > if (EFI_ERROR (Status)) { > DEBUG ((DEBUG_ERROR, "%a failed to generate random number: %r\n", __func__, Status)); > return Status; > } > This also introduces a new PCD to enable/disable the use of the secure implementation of algorithms for PseudoRandom () and instead depend on the default implementation. This may be required for some platforms where the UEFI Spec defined algorithms are not available. > > PcdEnforceSecureRngAlgorithms > If the platform does not have any one of the UEFI defined secure RNG algorithms then the driver will assert.
