Denial of Service in Mosix
------------------------------------------------------------------------
SUMMARY
<http://www.mosix.org/> Mosix is a set of kernel patches and a few
utilities that allows Linux processes to be migrated from one host to
another. This allows heavily used machines to migrate processes to
machines with a lower load. There are almost no limits to this: hard disk
and other resources can be accessed by the migrated processes as usual and
they seem in all ways to be running on the server. Mosix is vulnerable to
a Denial of Service attack. The vulnerability lies in the
mosix-protocol-stack, causing the Mosix to not handle garbage-packets
correctly.
DETAILS
Vulnerable systems:
Mosix version 1.5.7
By sending garbage packets to the Mosix server, it is possible to cause
the product to crash, effectively causing a denial of service attack
against the Mosix hosting cluster.
