Descriptions

EDK2'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.

EDK2's Network Package es susceptible a una vulnerabilidad de desbordamiento de búfer a través de una opción de ID de servidor larga en el cliente DHCPv6. Un atacante puede aprovechar esta vulnerabilidad para obtener acceso no autorizado y potencialmente provocar una pérdida de confidencialidad, integridad y/o disponibilidad.

A security flaw was identified in EDK2, the open-source reference implementation of the UEFI specification, involving a buffer overflow vulnerability. This particular weakness enables an unauthorized attacker within the vicinity of the network to transmit a specifically crafted DHCPv6 message. This, in turn, could result in an information disclosure and compromise the availability of the system.
