From: Michael Kubacki <michael.kubacki@...>

Adds queries for the following:

1. cpp/conditionallyuninitializedvariable
2. cpp/pointer-overflow-check
3. cpp/overrunning-write
4. cpp/overrunning-write-with-float
5. cpp/very-likely-overrunning-write

These check for vulnerabilities with the following CWEs:

- https://cwe.mitre.org/data/definitions/120.html
- https://cwe.mitre.org/data/definitions/457.html
- https://cwe.mitre.org/data/definitions/676.html
- https://cwe.mitre.org/data/definitions/758.html
- https://cwe.mitre.org/data/definitions/787.html
- https://cwe.mitre.org/data/definitions/805.html

The first part of this patch series contains fixes for CodeQL alerts
across various packages that are produced by the new queries being
enabled.

The second part updates the CodeQL queries.

V2 series changes:

1. MdeModulePkg/Universal/SmbiosDxe/SmbiosDxe.c
- Applied SafeUintnAdd() to both variables in the comparison
in ParseAndAddExistingSmbiosTable()

Addresses feedback from: Mike Kinney

2. CryptoPkg/Library/BaseCryptLib/Pk/CryptX509.c
- Changes:

if (!(Inf & 0x80) && (Asn1Tag !=3D V_ASN1_SEQUENCE)) {

To:

if (!(Inf & 0x80) && (Asn1Tag !=3D V_ASN1_SEQUENCE)) {

Addresses feedback from: Mike Kinney

3. MdePkg/Library/BaseLib/String.c
- Removes: #include <Uefi/UefiBaseType.h>
- Changes conditional style in changes to if statement from
ternary for changes made throughout the file
- Updates commit message to describe change in return value

Addresses feedback from: Mike Kinney

4. NetworkPkg/Library/DxeHttpLib/DxeHttpLib.c
- Changes:

if (!EFI_ERROR (Status) && (Data > HTTP_URI_PORT_MAX_NUM)) {
Status =3D EFI_INVALID_PARAMETER;
goto ON_EXIT;
}

To:

if (EFI_ERROR (Status) || (Data > HTTP_URI_PORT_MAX_NUM)) {
Status =3D EFI_INVALID_PARAMETER;
goto ON_EXIT;
}

Addresses feedback from: Mike Kinney

5. ShellPkg/Application/Shell/Shell.c
- Initializes CalleeStatus to EFI_SUCCESS in DoStartupScript()
- Restores original if statement logic in DoStartupScript()

Addresses feedback from: Zhichao Gao

6. ShellPkg/Application/Shell/ShellProtocol.c
- Adds additional check for return value from
PARSE_HANDLE_DATABASE_UEFI_DRIVERS() in EfiShellGetDeviceName()

Addresses feedback from: Zhichao Gao

7. Includes up-to-date R-b tags
