Serious flaws patched for Adobe Reader and Windows 2000

Adobe timed the release of a critical patch for Reader with a barely-there Patch Tuesday.

Today's post-holiday Patch Tuesday included just one bulletin, which is rated critical only for Windows 2000, but Adobe also released a must-have Reader update.

Microsoft's MS10-001 security bulletin addresses a flaw with Embedded OpenType fonts that can be attacked through any program that can render the fonts, including Internet Explorer, PowerPoint or Word. A successful attack could hand over complete control of a vulnerable system, according to the bulletin, but only Windows 2000 is vulnerable.

Other versions of Windows "contain the vulnerable code but do not use this code in a way that may expose the vulnerability," according to the bulletin. If you have a Windows 2000 system you'll get this fix via Windows Update.

On the other hand, all Windows, Macintosh and Unix systems with Adobe Reader 9.2 or Acrobat 9.2 will need a program update to version 9.3 to close an under-attack security flaw that has been targeted with poisoned .pdf files. Acrobat versions 8.1.7 and earlier will likewise require an upgrade to version 8.2. Heading to Help | Check for Updates will get you the update, or download the full 9.3 version. For more details see Adobe's bulletin.

I need power and lots of it. As a Front End Web developer anything less just won’t cut it which is why the MSI GT75 is an outstanding laptop for me. It’s a sleek and futuristic looking, high quality, beast that has a touch of sci-fi flare about it.

MSI GS65 Stealth Thin

If you can afford the price tag, it is well worth the money. It out performs any other laptop I have tried for gaming, and the transportable design and incredible display also make it ideal for work.
