EmbeddedPkg/Hob: Integer Overflow in CreateHob()
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4166
Fix integer overflow in various CreateHob instances.
Fixes: CVE-2022-36765
The CreateHob() function aligns the requested size to 8
performing the following operation:
```
HobLength = (UINT16)((HobLength + 0x7) & (~0x7));
```
No checks are performed to ensure this value doesn't
overflow, and could lead to CreateHob() returning a smaller
HOB than requested, which could lead to OOB HOB accesses.

MdePkg/BaseRngLib: Add a smoketest for RDRAND and check CPUID
RDRAND has notoriously been broken many times over its lifespan.
Add a smoketest to RDRAND, in order to better sniff out potential
security concerns.
Also add a proper CPUID test in order to support older CPUs which may
not have it; it was previously being tested but then promptly ignored.
Testing algorithm inspired by linux's arch/x86/kernel/cpu/rdrand.c
:x86_init_rdrand() per commit 049f9ae9..
Many thanks to Jason Donenfeld for relicensing his linux RDRAND detection
code to MIT and the public domain.

NetworkPkg TcpDxe: Fixed system stuck on PXE boot flow in iPXE environment
This bug fix is based on the following commit "NetworkPkg TcpDxe: SECURITY PATCH"
REF: 1904a64
Issue Description:
An "Invalid handle" error was detected during runtime when attempting to destroy a child instance of the hashing protocol. The problematic code segment was:
NetworkPkg\TcpDxe\TcpDriver.c
Status = Hash2ServiceBinding->DestroyChild(Hash2ServiceBinding, ​&mHash2ServiceHandle);
Root Cause Analysis:
The root cause of the error was the passing of an incorrect parameter type, a pointer to an EFI_HANDLE instead of an EFI_HANDLE itself, to the DestroyChild function. This mismatch resulted in the function receiving an invalid handle.
Implemented Solution:
To resolve this issue, the function call was corrected to pass mHash2ServiceHandle directly:
NetworkPkg\TcpDxe\TcpDriver.c
Status = Hash2ServiceBinding->DestroyChild(Hash2ServiceBinding, mHash2ServiceHandle);
This modification ensures the correct handle type is used, effectively rectifying the "Invalid handle" error.
Verification:
Testing has been conducted, confirming the efficacy of the fix. Additionally, the BIOS can boot into the OS in an iPXE environment.

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.

JIRA: https://issues.redhat.com/browse/RHEL-40270
Upstream: Merged
CVE: CVE-2023-45237
Conflicts: Cherry pick wanted to add include files from the
missing 'add ShellComponents' (commit 2cb466cc2cbf...)
series. This had to be handled manually.
commit 712797cf19acd292bf203522a79e40e7e13d268b
Author: Gerd Hoffmann <kraxel@redhat.com>
Date: Fri May 24 12:51:17 2024 +0200
OvmfPkg: wire up RngDxe
Add OvmfRng include snippets with the random number generator
configuration for OVMF. Include RngDxe, build with BaseRngLib,
so the rdrand instruction is used (if available).
Also move VirtioRng to the include snippets.
Use the new include snippets for OVMF builds.

SecurityPkg/RngDxe: add rng test
Check whenever RngLib actually returns random numbers, only return
a non-zero number of Algorithms if that is the case.
This has the effect that RndDxe loads and installs EFI_RNG_PROTOCOL
only in case it can actually deliver random numbers.

CVE: CVE-2022-36765
Upstream: Merged
commit 9a75b030cf27d2530444e9a2f9f11867f79bf679

StandaloneMmPkg/Hob: Integer Overflow in CreateHob()
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4166
Fix integer overflow in various CreateHob instances.
Fixes: CVE-2022-36765
The CreateHob() function aligns the requested size to 8
performing the following operation:
```
HobLength = (UINT16)((HobLength + 0x7) & (~0x7));
```
No checks are performed to ensure this value doesn't
overflow, and could lead to CreateHob() returning a smaller
HOB than requested, which could lead to OOB HOB accesses.
