Welcome to the Network Security website at the IAS

This website is intended to bring you the latest news, how to's, tools and resources in Information Security.  Security Awareness of our Faculty, Members and Staff is key in creating a safer computing environment.

The three major Principles of Information Security, Availability, Integrity and Confidentiality, will be covered throughout the security awareness program at the Institute.  For a description of these principles, please see our About section.

In keeping with the spirit of the Institute, I encourage questions and open discussions about security.  And if you discover anything out of the ordinary, please feel free to bring it to my attention so that we can work together to create a more productive, safer environment.

Thanks,
Brian Epstein <security@ias.edu>

Linux kernel vmsplice() local privilege escalation exploit

http://secunia.com/advisories/28835/ - A bug in the vmsplice() call in the Linux kernel can allow a local user to escalate privileges to root. Sample code is available and has been verified as working. This bug affects kernel version 2.6.17 - 2.6.24.1, although the privilege escalation only works in the extended version of vmsplice() in 2.6.23 - 2.6.24. A patch partially fixing the bug is available in 2.6.24.2.
