Hole in Linux kernel provides root rights

“A flaw in the implementation of the Reliable Datagram Sockets
protocol (RDS) in the Linux kernel can be exploited to gain root
(also known as superuser) rights or permissions on a victim’s
system.

“Attackers can exploit the hole to get complete control remotely
once they have broken into the system. Dan Rosenberg, who
discovered the vulnerability, has published an exploit for
demonstration purposes; in a test conducted by The H’s associates
at heise Security on Ubuntu 10.04 (64-bit), it opened a root
shell.”
