CNET reported on a recent study by Sophos about the web habits of Facebook users.  Their study found that 41-46% of users blindly accepted friend requests from two unknown people.  Sophos was then able to access "up to 89 percent of the users' full dates of birth, all of their e-mail addresses, where they went to school, and more."

Vulnerabilities in the Java Runtime Environment May Allow Privileges to be Escalated


"Multiple buffer and integer overflow vulnerabilities in the Java
Runtime Environment with processing audio and image files may allow an
untrusted applet or Java Web Start application to escalate privileges.

BlackBerry Attachment Service PDF Distiller Multiple Remote Code Execution Vulnerabilities


"BlackBerry Attachment Service is prone to multiple remote
code-execution vulnerabilities when handling specially crafted PDF files.

Attackers can leverage these issues to corrupt memory and execute
arbitrary code in the context of the vulnerable service, possibly with
SYSTEM-level privileges. Successful exploits will compromise the server.
Failed attacks will likely result in denial-of-service conditions. "

Seasoned Unix admins may already know the pitfalls of blindly running
ldd on unknown executables. However, since this article was recently
released, I thought it might be good as a reminder to everyone to be
careful when using it.

This article shows some techniques on how to cause ldd to run arbitrary
code, and how easy it is to trick a sysadmin into executing that code as
