This was not part of the Quarkslab bugs however the same pattern
as CVE-2023-45229 exists in Dhcp6UpdateIaInfo.
This patch replaces the code in question with the safe function
created to patch CVE-2023-45229
>
> if (EFI_ERROR (
> Dhcp6SeekInnerOptionSafe (
> Instance->Config->IaDescriptor.Type,
> Option,
> OptionLen,
> &IaInnerOpt,
> &IaInnerLen

> ))
> {
> return EFI_DEVICE_ERROR;
> }
>
Additionally corrects incorrect usage of macro to read the status
> - StsCode = NTOHS (ReadUnaligned16 ((UINT16 *)DHCP6_OFFSET_OF_OPT_LEN
(Option)));
> + StsCode = NTOHS (ReadUnaligned16 ((UINT16 *)
DHCP6_OFFSET_OF_STATUS_CODE (Option));

PixieFail Bug #4
CVE-2023-45232
CVSS 7.5 : CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
CWE-835 Loop with Unreachable Exit Condition ('Infinite Loop')
Infinite loop when parsing unknown options in the Destination Options
header
PixieFail Bug #5
CVE-2023-45233
CVSS 7.5 : CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H
CWE-835 Loop with Unreachable Exit Condition ('Infinite Loop')
Infinite loop when parsing a PadN option in the Destination Options
header
Change Overview:
Most importantly this change corrects the following incorrect math
and cleans up the code.
> // It is a PadN option
> //
> - Offset = (UINT8)(Offset + *(Option + Offset + 1) + 2);
> + OptDataLen = ((EFI_IP6_OPTION *)(Option + Offset))->Length;
> + Offset = IP6_NEXT_OPTION_OFFSET (Offset, OptDataLen);
> case Ip6OptionSkip:
> - Offset = (UINT8)(Offset + *(Option + Offset + 1));
> OptDataLen = ((EFI_IP6_OPTION *)(Option + Offset))->Length;
> Offset = IP6_NEXT_OPTION_OFFSET (Offset, OptDataLen);
Additionally, this change also corrects incorrect math where the calling
function was calculating the HDR EXT optionLen as a uint8 instead of a
uint16
> - OptionLen = (UINT8)((*Option + 1) * 8 - 2);
> + OptionLen = IP6_HDR_EXT_LEN (*Option) -
IP6_COMBINED_SIZE_OF_NEXT_HDR_AND_LEN;
Additionally this check adds additional logic to santize the incoming
data

CVE-2023-45235
CVSS 8.3 : CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:H
CWE-119 Improper Restriction of Operations within the Bounds of
a Memory Buffer
Buffer overflow when handling Server ID option from a DHCPv6 proxy
Advertise message
Change Overview:
Performs two checks
1. Checks that the length of the duid is accurate
> + //

> + }
2. Ensures that the amount of data written to the buffer is tracked and
never exceeds that
> + //
> + // Check that the option length is valid.
> + //
> + if ((DiscoverLen + OpLen + PXEBC_COMBINED_SIZE_OF_OPT_CODE_AND_LEN)
> DiscoverLenNeeded) {

Additional code clean up and fix for memory leak in case Option was NULL
