Subject: [SECURITY] New version of modutils released

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.
