CVE-2011-1012

Published: 1 March 2011

The ldm_parse_vmdb function in fs/partitions/ldm.c in the Linux kernel before 2.6.38-rc6-git6 does not validate the VBLK size value in the VMDB structure in an LDM partition table, which allows local users to cause a denial of service (divide-by-zero error and OOPS) via a crafted partition table.

From the Ubuntu security team

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