Debian Security Advisory                             security@debian.org

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.



wget url

        will fetch the file for you

dpkg -i file.deb

        will install the referenced file.





Debian GNU/Linux 2.1 alias slink

--------------------------------



  Slink is no longer being supported by the Debian Security Team.  We

  highly recommend an upgrade to the current stable release.





Debian GNU/Linux 2.2 alias potato

---------------------------------



  Potato was released for the Alpha, ARM, Intel ia32, Motorola 680x0,

  PowerPC and Sun Sparc architectures.  Fixes are available for all of

  them and will be included in 2.2r2.
