ObQuote:

There are two bugs present in Linux kernels 2.2.x, x<=19 and 2.4.y, y<=9.
The first vulnerability results in local DoS. The second one, involving
ptrace, can be used to gain root privileges locally (in case of default
install of most popular distributions). Linux 2.0.x is not vulnerable to the
ptrace bug mentioned.
