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>

VMSA-2011-0010: Third Party Updates for Service Console packages glibc and dhcp

Submitted by securityadmin on

"The DHCP client daemon, dhclient, does not properly sanatize certain
options in DHCP server replies. An attacker could send a specially
crafted DHCP server reply, that is saved on the client system and
evaluated by a process that assumes the option is trusted. This could
lead to arbitrary code execution with the privileges of the evaluating
process."

Apple released an update for iOS devices that addresses a major
vulnerability with insecure SSL/TLS connections and x509 certificate
handling. Programs currently exist in the wild that can easily hijack a
purportedly "secure" connection from an afflicted device.

ISC BIND 9 Remote packet Denial of Service against Authoritative and Recursive Servers

Submitted by securityadmin on

http://www.isc.org/software/bind/advisories/cve-2011-2464

"A defect in the affected BIND 9 versions allows an attacker to remotely
cause the "named" process to exit using a specially crafted packet. This
defect affects both recursive and authoritative servers. The code
location of the defect makes it impossible to protect BIND using ACLs
configured within named.conf or by disabling any features at
compile-time or run-time."
