The Continuing Saga of Malware by Email

We’re seeing reports of a new round of storm virus emails. This time they’re using valentine’s day to lure users to a site to download and run the malware. Otherwise it is essentially the same attack as before. We advise that you ensure all your email and virus defenses are running with the latest updates and that your users are reminded to ignore emails from unknown entities. They should also never download attachments from emails or web sites that are not explicitly trusted. There are plenty of potentially intriguing subjects that could be used to dup unsuspecting users. Things like winning Super Bowl tickets, checking out the latest American Idol videos, or even the latest news on the presidential campaign.

Quicktime PoC

Apple released an update to Quicktime yesterday, and attackers wasted no time coming up with a new exploit for it. Already in the public is a proof of concept exploit for Quicktime It seems that Apple still hasn’t fixed the root cause of the RTSP vulnerability.

In other news, a survey over the past year on Oracle admins found that only 1 in 3 Oracle database admins bother to patch their databases. 68% of the admins admitted to never applying any patches at all. If that is true, it’s rather frightening.

QuickTime 7.3.1 is available

Apple has released QuickTime 7.3.1 to address several vulnerabilities. These include the buffer overflow in RTSP, a heap buffer overflow found in QuickTime’s handling of QTL files and vulnerabilities which exist in QuickTime’s Flash media handler.

Level One WBR-3460A Wireless Router Telnet Vulnerability

This device presents a telnet prompt on the standard port (23/tcp). This instance of telnet allows local users to login without authenticating. This gives the user access to the file system where they are able to manipulate files or grab the administrator password for the web interface. A fix is in development.
