Linux kernel 2.6.18, and possibly other versions, when running on AMD64
architectures, allows local users to cause a denial of service (crash) via
certain ptrace calls.
Jan Kratochvil discovered that PTRACE did not correctly handle certain
calls when running under 64bit kernels. A local attacker could exploit
this to crash the system, leading to a denial of service.
