Subject: [PATCH 05/19] NetworkPkg: Dhcp6Dxe: SECURITY PATCH CVE-2023-45229
Unit Tests
REF: https://bugzilla.tianocore.org/show_bug.cgi?id=4534
These tests confirm that the report bug...
"Out-of-bounds read when processing IA_NA/IA_TA options in a
DHCPv6 Advertise message"
..has been patched.
The following functions are tested to confirm an out of bounds read is
patched and that the correct statuses are returned:
Dhcp6SeekInnerOptionSafe
Dhcp6SeekStsOption
TCBZ4534
CVE-2023-45229
CVSS 6.5 : CVSS:3.1/AV:A/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N
