REF:https://bugzilla.tianocore.org/show_bug.cgi?id=4537 REF:https://bugzilla.tianocore.org/show_bug.cgi?id=4538 Bug Details: 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 Cc: Saloni Kasbekar <saloni.kasbekar@intel.com> Cc: Zachary Clark-williams <zachary.clark-williams@intel.com> Signed-off-by: Doug Flick [MSFT] <doug.edk2@gmail.com> Reviewed-by: Saloni Kasbekar <saloni.kasbekar@intel.com>

This patch does not impact functionality. It aims to clarify the synchronization flow between the BSP and APs to enhance code readability and understanding: Steps #6 and #11 are the basic synchronization requirements for all cases. Steps #1 is additional requirements if the MmCpuSyncModeTradition mode is selected. Steps #1, #2, #3, #4, #5, #7, #8, #9, and #10 are additional requirements if the system needs to configure the MTRR. Steps #9 and #10 are additional requirements if the system needs to support the mSmmDebugAgentSupport. Signed-off-by: Jiaxin Wu <jiaxin.wu@intel.com>
