Description:
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.
Ubuntu-Description:
Mathias Krause discovered that the Linux kernel did not correctly handle
missing ELF interpreters. A local attacker could exploit this to cause
the system to crash, leading to a denial of service.
