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
- SecurityPkg was updated to fix an incorrect limitation on the
GetRng function in the RngDxe driver where the minimum amount of
random data that could be requested was 32 bytes (256 bits) instead
of what the caller requested
- 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
- ArmPkg was updated to allow the SMC/HVC monitor conduit to be
specified at runtime
- MdePkg was updated to remove an overzealous ASSERT in BaseRngLib
- ArmVirtPkg was updated to permit the use of dynamic PCDs in PEI
- ArmVirtPkg was updated to use dynamic PCDs to set the SMCCC conduit
- ArmVirtPkg was updated to add the RngDxe driver

Removed from gEfiRngAlgorithmRaw an incorrect assumption that
Raw cannot return less than 256 bits. The DRNG Algorithms
should always use a 256 bit seed as per nist standards
however a caller is free to request less than 256 bits.

AARCH64 platforms do not have this limitation and this brings both
implementations into alignment with each other and the spec.

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.

PixieFail Bug #8
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.

ArmVirtQemu may execute at EL2, in which case monitor calls are
generally made using SMC instructions instead of HVC instructions.
Whether or not this is the case can only be decided at runtime, and so
the associated PCD needs to be settable at runtime, if the platform
definition chooses so. This implies a boolean PCD, given that a feature
PCD is build-time configurable only.

From: Ard Biesheuvel <ardb@kernel.org>
BaseRngLib on AARCH64 will discover whether or not RNDR instructions are
supported, by inspecting the ISAR0 identification register, and setting
a global boolean accordingly. This boolean is used in subsequent
execution to decide whether or not to issue the instruction.
The same discovery code also ASSERT()s that RNDR instructions are
implemented, which is unnecessary, and breaks execution on systems that
incorporate the library but don't implement the instruction (or fail to
expose it to the exception level that the firmware executes at).
So drop the ASSERT().

for being able to use dynamic PCDs already at the PEI stage. This
facility will be used for other reasons too so move those pieces out of
code block that are conditional on TPM2_ENABLE

From: Ard Biesheuvel <ardb@kernel.org>
On ARM systems, whether SMC or HVC instructions need to be used to issue
monitor calls is typically dependent on the exception level, but there
are also cases where EL1 might use SMC instructions, so there is no hard
and fast rule.
For ArmVirtQemu, this does depend strictly on the exception level, so
set the default to HVC (for EL1 execution) and override it to SMC when
booted at EL2.

MdeLibs.inc sets default library class resolutions which are much more
general than the ones that might be specified in ArmVirt.dsc.inc. So the
latter should be included *after* MdeLibs.inc to ensure that its
definitions take precedence.

Add the RngDxe driver to the build, backed by either RNDR or TRNG, one
of which is expected to be available in most cases:
- RNDR is implemented by the 'max' CPU that QEMU implements in TCG mode
- TRNG is implemented by the KVM hypervisor, which backs QEMU's 'host'
CPU
Other TCG modes (e.g., the 'cortex-a*' CPUs) implement neither, which
should prevent the RngDxe driver from dispatching entirely, resulting
in the same situation as before.

Bug Overview:
PixieFail Bug #8
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.
