CVE-2011-1577

Published: 3 May 2011

Heap-based buffer overflow in the is_gpt_valid function in fs/partitions/efi.c in the Linux kernel 2.6.38 and earlier allows physically proximate attackers to cause a denial of service (OOPS) or possibly have unspecified other impact via a crafted size of the EFI GUID partition-table header on removable media.

From the Ubuntu security team

Timo Warns discovered that the GUID partition parsing routines did not correctly validate certain structures. A local attacker with physical access could plug in a specially crafted block device to crash the system, leading to a denial of service.
