Earlier this morning, Virtual Stock Exchange (VSTEX) Public Relations Officer Samantha Goldflake announced that VSTEX had halted all companies on their exchange and asked users not to withdraw funds via their ATMs. Goldflake informed me that while she could not provide specifics, the situation was severe enough to warrant an open discussion with the CEOs of all SL exchanges.

I have tried to stay away from the security issue, not because I don't think it's important but because I didn't want to spread panic when I only have half the facts.

After Konner posted on the halt of the Exchanges, Ciaran hit the nail on the head about the silence of Linden Lab on the topic. I've been following it with interest, trying to nail down exactly how the exploit occurred, when I found it in my email - I'm withholding the person's name at this point, but I can share that the information has been disseminated to the exchanges.
