Subject: Registration Weakness in Linux Kernel's Binary formats
To: undisclosed-recipients


Hello,
The present document aims to demonstrate a design weakness found in the
handling of simply
linked   lists   used   to   register   binary   formats   handled   by
Linux   kernel,   and   affects   all   the   kernel families
(2.0/2.2/2.4/2.6), allowing the insertion of infection modules in
kernel­ space that can be used by malicious users to create infection
tools, for example rootkits.

POC, details and proposed solution at:
English version: http://www.shellcode.com.ar/docz/binfmt-en.pdf
Spanish version: http://www.shellcode.com.ar/docz/binfmt-es.pdf

regards,
