This patch (9.2.7) may fix a security hole in OOTP9 that may have allowed for some of the attacks. The first "may" is because OOTP hasn't publicly announed the patch so I don't what it does or doesn't fix, but at least one person that knows this stuff thinks that it probably does. The second "may" is because we don't know what may have allowed the attacks, it could have been something else, but it appears it may just have been OOTP itself. See the above linked thread for more info.
