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>

http://seclists.org/fulldisclosure/2010/Jan/397

For anyone still on Debian 4.0, now is a good time to work on a
migration plan to Debian 5.0. Debian will stop releasing security
updates after February 15th for 4.0.

This is also a good time for Ubuntu users to check their distribution
for similar announcements. Ubuntu is based on Debian.

RHEL5 kernel security and bug fix update

https://rhn.redhat.com/errata/RHSA-2010-0046.html

Here is a new kernel update, unrelated to the last update sent out 9
days ago. It fixes a myriad of new problems including Denial of
Service, Privilege Escalation, kernel panic, file rewrite, and
information leaks to name a few.

It is recommended that RHEL5 systems be updated and rebooted to mitigate
the risk from these issues.

"Affected: Adobe Shockwave Player 11.5.2.602"

"Secunia Research has discovered four vulnerabilities in Adobe
Shockwave Player, which can be exploited by malicious people to
compromise a user's system.

when processing a certain block type. These can be exploited to cause
heap-based buffer overflows via specially crafted Shockwave files.
