Microsoft today said it will deliver just one security update next week, a fix for PowerPoint that's probably the patch for
a month-old bug that developers admitted they missed during stress testing.
Attackers exploit critical PowerPoint vulnerability
The single update, which will be labeled "critical," Microsoft's highest threat ranking, is a big drop from last month, when
the company issued eight updates that patched 23 vulnerabilities.
"Last month, Microsoft closed three of the four known outstanding vulnerabilities, and left us only one in-the-public-domain
bug," said Andrew Storms, director of security operations at nCircle Network Security Inc. The sole unpatched public flaw
was the PowerPoint vulnerability Microsoft acknowledged April 2 in a security advisory that warned of ongoing attacks using rigged presentation files.
"The question, is there a pattern here, have they caught up?" asked Storms. "Could we have hit bottom?"
But he immediately dismissed that idea. "Don't think for a minute that I believe that," Storms said. "Microsoft has done a
fantastic job of getting people to report [vulnerabilities] only to them, but that doesn't mean there are no other bugs. Frankly,
I expected more than just the one."
As is Microsoft's practice, it released only the most general information about the upcoming security patch in the advance notification it posted Thursday. Unlike the April security advisory, however, the early warning today noted that PowerPoint 2000, 2002,
2003 and 2007 will require patching; the advisory had not painted the newest version, PowerPoint 2007, with the bug brush.
Previously, Microsoft had admitted that the bug was in an older PowerPoint file format. The inclusion of PowerPoint 2007, Storms speculated, means that the new version may be affected when it tries to convert
from an older format to the Office 2007 native format.
The last time Microsoft issued only one update on a Patch Tuesday was in January, when it fixed flaws in Windows' Server Message Block (SMB) file-sharing protocol. At the time, another security expert, Eric Schultze, the chief
technology officer at Shavlik Technologies, called the bugs "super nasty."
"Don't get me wrong, I'm happy to have the PowerPoint patch," said Storms today.
