Descriptions

Heap-based buffer overflow in Shim allows remote attackers to execute arbitrary code via a crafted IPv6 address, related to the "tftp:// DHCPv6 boot option."

Desbordamiento de buffer basado en la memoria dinámica en Shim permite a atacantes remotos ejecutar código arbitrario a través de una dirección IPv6 manipulada, relacionado con la opción de arranque 'tftp:// DHCPv6.'

A heap-based buffer overflow flaw was found the way shim parsed certain IPv6 addresses. If IPv6 network booting was enabled, a malicious server could supply a crafted IPv6 address that would cause shim to crash or, potentially, execute arbitrary code.
