REF:https://blog.quarkslab.com/pixiefail-nine-vulnerabilities-in-tianocores-edk-ii-ipv6-network-stack.html
This patch series patches the following CVEs:
- CVE-2023-45236: Predictable TCP Initial Sequence Numbers
- CVE-2023-45237: Use of a Weak PseudoRandom Number Generator
In order to patch these CVEs, the following changes were made:
- NetworkPkg no longer performs it's own random number generation,
instead it uses EFI_RNG_PROTOCOL provided by the plaform to
generate random numbers.
- This change was made such that any future random number
generation vulnerabilities will be a result of the platforms
implementation of the EFI_RNG_PROTOCOL and not the NetworkPkg
- NetworkPkg uses the TCP initial sequence number algorithm as described
in RFC 6528 to generate the initial sequence number for TCP connections.
- This change was made to ensure that the initial sequence number
is not predictable and therefore cannot be used in a TCP hijacking
attack.
In addition to the above changes, the following changes were made:
- EmulatorPkg OvmfPkg, and ArmVirtPkg were updated to include the
Hash2DxeCrypto driver to support TCP ISN generation using
EFI_HASH2_PROTOCOL
- EmulatorPkg was updated to include the
RngDxe driver to support random number generation using the
EFI_RNG_PROTOCOL
- OvmfPkg, and ArmVirtPkg were updated to include the
virtio-rng-pci device to support random number generation using the
EFI_RNG_PROTOCOL using the existing VirtioRngDxe driver
- ArmVirtPkg and OvmfPkg were updated to disable the NIST algorithms
in the NetworkPkg due to the driver only supporting EFI_RNG_ALGORITHM
- MdePkg was updated to include MockUefiBootServicesTableLib,
MockRng, and MockHash2 protocols for testing
- NetworkPkg was updated to include a test for the PxeBcDhcp6 driver
due to underlying changes

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
NIST SP-800-90 approved 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 the NIST SP-800-90 approved algorithms
then the driver will assert.

CVE-2023-45236
CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:C/C:L/I:N/A:N
CWE-200 Exposure of Sensitive Information to an Unauthorized Actor
Updates TCP ISN generation to use a cryptographic hash of the
connection's identifying parameters and a secret key.
This prevents an attacker from guessing the ISN used for some other
connection.
This is follows the guidance in RFC 1948, RFC 6528, and RFC 9293.
RFC: 9293 Section 3.4.1. Initial Sequence Number Selection
A TCP implementation MUST use the above type of "clock" for clock-
driven selection of initial sequence numbers (MUST-8), and SHOULD
generate its initial sequence numbers with the expression:
ISN = M + F(localip, localport, remoteip, remoteport, secretkey)
where M is the 4 microsecond timer, and F() is a pseudorandom
function (PRF) of the connection's identifying parameters ("localip,
localport, remoteip, remoteport") and a secret key ("secretkey")
(SHLD-1). F() MUST NOT be computable from the outside (MUST-9), or
an attacker could still guess at sequence numbers from the ISN used
for some other connection. The PRF could be implemented as a
cryptographic hash of the concatenation of the TCP connection
parameters and some secret data. For discussion of the selection of
a specific hash algorithm and management of the secret key data,
please see Section 3 of [42].
For each connection there is a send sequence number and a receive
sequence number. The initial send sequence number (ISS) is chosen by
the data sending TCP peer, and the initial receive sequence number
(IRS) is learned during the connection-establishing procedure.
For a connection to be established or initialized, the two TCP peers
must synchronize on each other's initial sequence numbers. This is
done in an exchange of connection-establishing segments carrying a
control bit called "SYN" (for synchronize) and the initial sequence
numbers. As a shorthand, segments carrying the SYN bit are also
called "SYNs". Hence, the solution requires a suitable mechanism for
picking an initial sequence number and a slightly involved handshake
to exchange the ISNs.

This conflates 'secure' with 'specified by NIST', which I don't think
is entirely accurate.

I don't disagree.
The intent is not to be limited by NIST specified standards but rather the only UEFI Spec defined algorithms are NIST Standards.
https://uefi.org/specs/UEFI/2.10/37_Secure_Technologies.html#efi-rng-algorithm-definitions
I'm not sure what's the best way to clarify this distinction

The issue here is that virtio-rng only exposes the 'raw' RNG protocol,
which is what the underlying hardware claims to implement.
This has a special status in the spec, as it can be used as an entropy
source for the NIST algorithms, the security strength of which is
cannot exceed the security strength represented by the size of the
seed consumed from the raw input.
So in that sense, it might be appropriate to treat the raw protocol in
the same way as the NIST ones, and permit them, call them 'secure'
etc. Only when taking the default (ergo unspecified) algorithm should
we conclude that the algorithm may be less strong than what the spec
requires.
What would help is if RngDxe could wrap an implementation of the raw
RNG protocol produced by another driver, and produce the NIST DRBGs
based on that - perhaps I should look into that.

In that case,
I think that's a fair argument and a simple enough request with limited impact to make.
I'll go ahead and add RAW and drop the commits disabling "Secure Algorithms" from VirtioRngDxe based implementations

Ard,
I went ahead an added your suggestion to use gEfiRngAlgorithmRaw. This however led me to discover a difference in behavior in x86 based platforms and Arm based platforms and I'm usure which is the correct behavior.
On x86 based platforms, if the RngValueLength being requested is less than 32 (256bits). Then it returns EFI_INVALID_PARAMETER (despite the function header not indicating that's possible)
https://github.com/tianocore/edk2/blob/b82c9631da39ca5a1f0702185a46fea60446dd0a/SecurityPkg/RandomNumberGenerator/RngDxe/Rand/RngDxe.c#L123
and it assumes that "When a Deterministic Random Bit Generator (DRBG) is used on the output of a (raw) entropy source, its security level must be at least 256 bits." means it shouldn't support requests smaller than 32 bytes.
https://uefi.org/specs/UEFI/2.10/37_Secure_Technologies.html#random-number-generator-protocol
On Arm based Platforms it doesn't make this assumption and behaves according to the specification.
https://github.com/tianocore/edk2/blob/b82c9631da39ca5a1f0702185a46fea60446dd0a/SecurityPkg/RandomNumberGenerator/RngDxe/ArmRngDxe.c#L106C35-L106C54
Right now my thought is that x86 machines are making an incorrect assumption where the seed to a DRNG needs to be at least 256 bits by nist recommendations but a caller should be free to request values smaller than 32 bytes.
Would you assume the same before I make a change to the x86 code to remove that check?

I've always found that logic rather bizarre - there is no way the
implementation of the raw protocol can ensure that the caller uses it
correctly, and so enforcing a minimum read size is pointless and
arbitrary. And as you note, it has no basis in the UEFI spec either.
So this should just be removed imo.

For what it's worth, I agree that it should be removed.
iPXE has the following comment:
/** Minimum number of bytes to request from RNG
*
* The UEFI spec states (for no apparently good reason) that "When a
* Deterministic Random Bit Generator (DRBG) is used on the output of
* a (raw) entropy source, its security level must be at least 256
* bits." The EDK2 codebase (mis)interprets this to mean that the
* call to GetRNG() should fail if given a buffer less than 32 bytes.
*
* Incidentally, nothing in the EFI RNG protocol provides any way to
* report the actual amount of entropy returned by GetRNG().
