Descriptions
The is_gpt_valid function in fs/partitions/efi.c in the Linux kernel before 2.6.39 does not check the size of an Extensible Firmware Interface (EFI) GUID Partition Table (GPT) entry, which allows physically proximate attackers to cause a denial of service (heap-based buffer overflow and OOPS) or obtain sensitive information from kernel heap memory by connecting a crafted GPT storage device, a different vulnerability than CVE-2011-1577.
La función is_gpt_valid en fs/partitions/efi.c en el kernel de Linux v2.6.39 no comprueba el tamaño de una Tabla de particiones GUID (GPT) de un Interface Firmware Extensible (EFI), lo que permite causar a atacantes físicamente próximos una denegación de servicio (desbordamiento de memoria basado en monticulo y OOPS) u obtener información confidencial de la memoria dinámica del kernel conectando un dispositivo GPT de almacenamiento hecho a mano. Se trata de una vulnerabilidad diferente a CVE-2011-1577.
