We appreciate updates
US based customers can call Microsoft for free patch related support on 1-866-PCSAFETY
- We use 4 levels:
- PATCH NOW: Typically used where we see immediate danger of exploitation. Typical environments will want to deploy these patches ASAP. Workarounds are typically not accepted by users or are not possible. This rating is often used when typical deployments make it vulnerable and exploits are being used or easy to obtain or make.
- Critical: Anything that needs little to become "interesting" for the dark side. Best approach is to test and deploy ASAP. Workarounds can give more time to test.
- Important: Things where more testing and other measures can help.
- Less Urgent: Typically we expect the impact if left unpatched to be not that big a deal in the short term. Do not forget them however.
- The difference between the client and server rating is based on how you use the affected machine. We take into account the typical client and server deployment in the usage of the machine and the common measures people typically have in place already. Measures we presume are simple best practices for servers such as not using outlook, MSIE, word etc. to do traditional office or leisure work.
- The rating is not a risk analysis as such. It is a rating of importance of the vulnerability and the perceived or even predicted threat for affected systems. The rating does not account for the number of affected systems there are. It is for an affected system in a typical worst-case role.
- Only the organization itself is in a position to do a full risk analysis involving the presence (or lack of) affected systems, the actually implemented measures, the impact on their operation and the value of the assets involved.
- All patches released by a vendor are important enough to have a close look if you use the affected systems. There is little incentive for vendors to publicize patches that do not have some form of risk to them

Adobe June Black Tuesday upgrades
In the past it was by accident, but from now on it'll be by policy: Adobe will add to the workload by releasing their patches on a quarterly schedule to concide with the Microsoft monthly scheme.
June yielded just one bulletin:
Affects Acrobat (Reader) on Windows and Mac to Adobe Reader 9.1.2 and Acrobat 9.1.2. Also available are Acrobat 8.1.6 and Acrobat 7.1.3.
This fixes following CVE names:
CVE-2009-0198, CVE-2009-0509, CVE-2009-0510, CVE-2009-0511, CVE-2009-0512, CVE-2009-0888, CVE-2009-0889, CVE-2009-1855, CVE-2009-1856, CVE-2009-1857, CVE-2009-1858, CVE-2009-1859, and CVE-2009-1861.
Note that the bulletin states "Additionally, this update resolves Adobe internally discovered issues".
Among the list are a number of JBIG2 filter vulnerabilities.
JBIG2 filter vulnerabilities have been exploited in the past, so you really want this upgrade.
UPDATE:
Roseman wrote in to point out the bulletin contains: "Security updates for Adobe Reader on the UNIX platform will be available on June 16, 2009". which effectively gives the attackers time to reverse engineer the vulnerabilities from the patches for Windows and Mac and build exploits for the unix versions without those users having any chance to patch.

Safari 4.0 released - contains security fixes
Apple released yesterday an update to Safari 4.0 (which had been in beta for quite some time)
The release also contains a large number of fixes for security vulnerabilities:
CFNetwork: CVE-2009-1704, CVE-2009-1716
ImageIO: CVE-2009-0040
International components for Unicode: CVE-2009-0153
libxml: CVE-2008-3281, CVE-2008-3529, CVE-2008-4409, CVE-2008-4225, CVE-2008-4226
Safari: CVE-2009-1682, CVE-2009-1706, CVE-2009-1707, CVE-2009-1708
Safari windows installer (no CVE name)
Webkit: CVE-2006-2783, CVE-2008-1588, CVE-2008-2320, CVE-2008-3632, CVE-2008-4231, CVE-2009-1681, CVE-2009-1684, CVE-2009-1685, CVE-2009-1686, CVE-2009-1687, CVE-2009-1688, CVE-2009-1689, CVE-2009-1690, CVE-2009-1691, CVE-2009-1693, CVE-2009-1694, CVE-2009-1695, CVE-2009-1696, CVE-2009-1697, CVE-2009-1698, CVE-2009-1699, CVE-2009-1700, CVE-2009-1701, CVE-2009-1702, CVE-2009-1703, CVE-2009-1709, CVE-2009-1710, CVE-2009-1711, CVE-2009-1712, CVE-2009-1713, CVE-2009-1714, CVE-2009-1715, CVE-2009-1718
Needles to say, this update comes as highly recommended for anybody using safari.
Note some CVE names are quite old ... e.g. CVE-2006-2783 was first discussed more than 3 years ago in Mozilla (June 1st, 2006) and was fixed by Apple for iPhone and iPod almost a year ago (July 11th, 2008).
