Package: modutils
Vulnerability: local exploit
Debian-specific: no
Sebastian Krahmer found a problem in the modprobe utility that could
be exploited by local users to run arbitrary commands as root if the
machine is running a kernel with kmod enabled.
The kmod kernel feature allows the kernel to dynamically load kernel
modules if functionality is required that is not present in the
running kernel. It does this by invoking the modprobe command with
the requested module as parameter. This parameter can be influenced
by users, for example by opening a currently non-existing files on a
devfs filesystem, or trying to access a non-existing network
interface. Since modprobe did not properly escape shell
meta-characters when calling external commands or check if the last
parameters was an option instead of a modulename, users can cause it
to run arbitrary commands.
This has been fixed in version 2.3.11-12 and we recommend that you
upgrade your modutils package immediately.

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.
