Security Fix(es):


EDK2 is susceptible to a vulnerability in the Tcg2MeasurePeImage() function, allowing a user to trigger a heap buffer overflow via a local network. Successful exploitation of this vulnerability may result in a compromise of confidentiality, integrity, and/or availability.

(CVE-2022-36764)

 EDK2&apos;s Network Package is susceptible to a buffer overflow vulnerability via a long server ID option in DHCPv6 client. This
 vulnerability can be exploited by an attacker to gain unauthorized 
access and potentially lead to a loss of Confidentiality, Integrity and/or Availability.

(CVE-2023-45230)

 EDK2&apos;s Network Package is susceptible to an infinite loop vulnerability when parsing unknown options in the Destination Options header of IPv6. This
 vulnerability can be exploited by an attacker to gain unauthorized 
access and potentially lead to a loss of Availability.

(CVE-2023-45232)

 EDK2&apos;s Network Package is susceptible to an infinite lop vulnerability when parsing a PadN option in the Destination Options header of IPv6. This
 vulnerability can be exploited by an attacker to gain unauthorized 
access and potentially lead to a loss of Availability.

(CVE-2023-45233)

 EDK2&apos;s Network Package is susceptible to a buffer overflow vulnerability when





handling Server ID option 



 from a DHCPv6 proxy Advertise message. This
 vulnerability can be exploited by an attacker to gain unauthorized 
access and potentially lead to a loss of Confidentiality, Integrity and/or Availability.
