www.theregister.co.uk wrote:Here we go again: Critical flaw found in just-patched Java

Security Explorations, the Polish security startup that discovered the Java SE 7 vulnerabilities that have been the targets of recent web-based exploits, has spotted a new flaw that affects the patched version of Java released this Thursday.

The company would not disclose specific details on the nature of the new vulnerability because it does not release such information to the public – a reasonable precaution.

However, Security Explorations founder and CEO Adam Gowdiak was able to confirm that the defect does affect Java SE 7 Update 7, which Oracle released this week as a rare out-of-band patch.

"The bug is related to some of our previous bugs reported to Oracle in April 2012 (and not yet patched) in such a way so that it allows to exploit them again," Gowdiak told El Reg in an email.

As in the case of the earlier vulnerabilities, Gowdiak says, this flaw allows an attacker to bypass the Java security sandbox completely, making it possible to install malware or execute malicious code on affected systems.

Unlike the earlier vulnerabilities, no known exploit of the new flaw has yet been found in the wild, but Gowdiak says he included proof-of-concept code with the report to demonstrate that an exploit is indeed possible.

Oracle has not acknowledged that the new vulnerability actually exists, but it has confirmed that it has received Security Explorations' vulnerability report and is analyzing it.

Assuming Oracle does agree that the flaw exists, however, when it will be patched is anybody's guess. The next scheduled Java Critical Patch Update (CPU) isn't due until October 16 – and when Oracle released its last Java CPU in June, it had only patched two of the 31 flaws Security Explorations reported in April.

Oracle could release another emergency patch as it did this week, but such occasions have been rare for the database giant. It may be reluctant to do so again, given that the new flaw isn't known to be under active attack.

That's likely to happen soon, though. Now that the black hat community knows that a vulnerability exists, creating an exploit will only be a matter of locating it.

For the time being, given the apparent similarity of this flaw to the ones previously reported, users are advised to either disable Java in their browsers or uninstall it completely to avoid falling prey to any future exploits.

Maxis has since clarified that she intended to qualify that with statement “without a significant amount of engineering work,” as she did elsewhere on the same day. Those claims added fuel to the fire of angry customers, as a home-made offline-mode hack was already making the rounds.

The engineering work Bradshaw referred to, according to Buechner, was largely that Maxis had to completely rewrite much of the server code. Originally done in the Java programming language, it had to be redone in C++ in order to make it run locally on our PCs.

Every time I drink a cup of coffee I turn to the IT guy and say, "I just installed the latest Java update."

I think I may or may not be off of his Christmas list.
