OpenSSH Vulnerability
OpenSSH announced that OpenSSH 6.2 and 6.3 are vulnerable to an authenticated code execution flaw. The vulnerability affects the AES-GCM cipher. As a quick fix, you can disable the cipher (see the URL below for details). Or you can upgrade to OpenSSH 6.4.
A user may bypass restrictions imposed to the users account by exploiting the flaw, but the user needs valid credentials to take advantage of the flaw.

What Happened to the SANS Ads?
You may have noticed that the "ad" frame we use in the top right corner has been empty for the last couple days. Oddly, we didn't get a lot of complaints about that ;-)
The reason is pretty simple: The SANS ads are included via an iframe. However, iframes, as Smit B. Shah pointed out in an e-mail to the SANS webmaster, can also be used in clickjacking attacks. So we decided to implement a simple anti-clickjacking defense by adding the "X-Frame-Options: SAMEORIGIN" header to all sans.org pages. Of course, "isc.sans.edu" is not "sameorigin" and the ads no longer show up if your browser supports the header.
Yes, there are Javascript tricks to prevent clickjacking, but they are far from reliable. If you still see the ads: You probably should use a newer browser. Of course, we will exempt some pages (like the ads ;-) ) from the header in the future, but for now figured that adding the header is more important then showing ads.

distribute malware. Even if the URL listed on the ad shows a legitimate website, subsequent ad traffic can easily lead to a fake page. Different types of malware are distributed in this manner. I've seen IcedID (Bokbot), Gozi/ISFB, and various information stealers distributed through fake software websites that were provided through Google ad traffic. I submitted malicious files from this example to VirusTotal and found a low rate of detection, with some files not showing as malware at all. Additionally, domains associated with this infection frequently change. That might make it hard to detect.
