CVE-2010-0307 (http://nvd.nist.gov/nvd.cfm?cvename=CVE-2010-0307):
  The load_elf_binary function in fs/binfmt_elf.c in the Linux kernel
  before 2.6.32.8 on the x86_64 platform does not ensure that the ELF
  interpreter is available before a call to the SET_PERSONALITY macro,
  which allows local users to cause a denial of service (system crash)
  via a 32-bit application that attempts to execute a 64-bit
  application and then triggers a segmentation fault, as demonstrated
  by amd64_killer, related to the flush_old_exec function.
