Package        : modutils
Problem type   : local buffer overflow
Debian-specific: no

Sebastian Krahmer raised an issue in modutils.  In an ideal world
modprobe should trust the kernel to only pass valid parameters to
modprobe.  However he has found at least one local root exploit
because high level kernel code passed unverified parameters direct
from the user to modprobe.  So modprobe no longer trusts kernel input
and switches to a safemode.

This problem has been fixed in version 2.3.11-13.1 and we recommend
that you upgrade your modutils packages immediately.

This problem does not exist in the big elvis package.

  Slink is no longer being supported by the Debian Security Team.  We
  highly recommend an upgrade to the current stable release.

  Potato was released for the Alpha, ARM, Intel ia32, Motorola 680x0,
  PowerPC and Sun Sparc architectures.  Fixes are available for all of
