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>

Skype Bug May Expose Users to Malicious Code

http://www.theregister.co.uk/2011/08/22/skype_security_bug/

"The XSS, or cross-site scripting, vulnerability in Skype 5.5.0.113 is
the result of the voice-over-IP client failing to inspect user-supplied
phone numbers for malicious code, researcher Levent Kayan said. As a
result, attackers might be able to exploit the bug to inject commands or
scripts that hijack the machine running the program.

PHP 5.3.8 Released

http://www.php.net/archive/2011.php#id2011-08-23-1

This release fixes two bugs:
* Fixed - crypt() returns only the salt for MD5
* Reverted a change in timeout handling restoring PHP 5.3.6 behavior,
which caused mysqlnd SSL connections to hang

The first in the list is the security alert sent out a couple of days ago
advising all to hold off on updating PHP.
