“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.”
