"The kernel module loader in Linux 2.2 and Linux 2.4 kernels has a flaw
in ptrace. This hole allows local users to obtain root privileges by
using ptrace to attach to a child process that is spawned by the
kernel. Remote exploitation of this hole is not possible.

This advisory only covers kernel packages for the big and little
endian MIPS architectures. Other architectures will be covered by
separate advisories."

"Upgrade the kernel-images packages immediately.

For the stable distribution (woody) this problem has been fixed in
version 2.4.17-0.020226.2.woody1 of kernel-patch-2.4.17-mips
(mips+mipsel) and in version 2.4.19-0.020911.1.woody1 of
kernel-patch-2.4.19-mips (mips only).

The old stable distribution (potato) is not affected by this problem
for these architectures since mips and mipsel were first released with
Debian GNU/Linux 3.0 (woody)."
