Microsoft fixes IE, Office in big month of security updates

Microsoft has released patches to fix 19 critical holes in its software Tuesday, including five flaws in IE that should be patched immediately.

Microsoft released patches to fix 19 critical vulnerabilities in its software Tuesday, including five flaws in its Internet Explorer browser that security experts advise IT administrators to patch immediately.

The total of 11 security updates released for August is the largest round of Patch Tuesday updates Microsoft has released since last February and should give IT administrators plenty to do to secure their companies' systems. "People are going to be quite busy with this load," said Jason Miller, security data team leader for Shavlik Technologies, a patch-management software provider in St. Paul, Minnesota.

Six of the patches, which can be found on Microsoft's Web site, are rated as critical, while five are rated as important.

Miller and other security experts cited Microsoft Security Bulletin MS08-045, a Cumulative Security Update for Internet Explorer, as the top priority among this month's batch of updates. The update patches five privately reported vulnerabilities and one that already has been disclosed publicly and for which attack code already exists, which makes it a zero-day flaw.

Don Leatham, director of solutions and strategy for Lumension Security, said the fact that the IE vulnerabilities affect HTML (Hypertext Markup Language) is enough reason to make patching them of the utmost importance, since the opportunity for exploitation is so vast. "Every Web site in the world uses HTML," he said. Lumension, based in Scottsdale, Arizona, provides patch- and vulnerability-management software and services

Shavlik's Miller said that the IE patches and another critical update released Tuesday that fixes a vulnerability in the ActiveX Control for the Snapshot Viewer for Microsoft Access -- MS08-041 -- are related because they both allow an attacker to create a Web site that takes advantage of these vulnerabilities. He listed them both as priorities for immediate installation.

Leatham also cited the Snapshot Viewer exploit as a high priority for IT administrators because many businesses use Access and its Snapshot Viewer tool extensively.

"You can be assured people are using the viewer to share information with partners, customers and internally given the popularity of the Office suite and how much businesses tend to use Access," he said.

An update that fixes a vulnerability in the Microsoft Windows Image Color Management System -- MS08-046 -- also should be installed immediately because it could allow an attack if a user navigates to a Web page and views a particular graphic, researchers said. The color-management system is part of the graphical subsystem of Windows.

"Given that [the vulnerability] is Web-based and graphical, you definitely want to pay some special attention to that one," Leatham said.

Two August updates rated as important also should be of interest to IT professionals, even if Microsoft has rated them below the critical updates. They are MS08-047, which fixes a vulnerability in IPsec Policy processing, and MS08-50, which patches a flaw in Messenger.

For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.

LIFEBOOK UH574

The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.

STYLISTIC Q702

The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.

STYLISTIC Q702

My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
