Registration Weakness in Linux Kernel's Binary formats

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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:
