Security flaw in older versions of MS Office…

[CNET News.com]
is reporting Flaw found in older Office versions.

“A security company warned Thursday that a flaw in Microsoft Office could allow a denial-of-service attack to be executed on systems running somewhat older versions of the popular productivity suite.

Secunia issued an advisory saying a buffer overrun flaw has been found in Office 2000, and potentially also in Office XP, that could allow hackers to take over a user’s system. The company rated the flaw as “highly critical.”

The security firm said that vulnerability is caused by an error in the way Microsoft Word manages input when parsing document files. It said the flaw could be exploited through a specially-crafted document and recommends that, until a fix is found, users only open trusted Word documents. “

Reminder: only open trusted attachments. Reminder 2: there are no trusted attachments.

Never open a document you are not expecting. Confirm all unexpected documents with the sender before opening.

Better yet, send documents as text or RTF if the recipient really doesn’t need all the features of a word processing document.

I wonder how OpenOffice.org would work with one of these broken documents…

FireFox security update

And speaking of FireFox, if you are running the latest 1.0 Preview Release, make sure to update with the latest security bug fix. Read the instructions carefully: the fix takes but a second: http://www.mozilla.org/press/mozilla-2004-10-01-02.html

Hacking the LinkSys WRT-54G

LinkSys manufactures a router-switch-wireless access point that’s a spiffy little computer on top of being a cute computer peripheral. The machine sports a 200 MHz ARM processor, 4 Mb of Flash RAM and 8 Mb or RAM. (Their new GS models doubles both of these). It is managed via a web interface. Not surprisingly, the device runs Linux. Since they base their code on Linux, the GNU Public License requires them to publish the source code as well. Naturally, this leads to third parties offering enhancements and replacements. Cool stuff includes:

  • Sveasoft offers a replacement with the BusyBox command shell, DropBear SSH server and dozens of other tools, as well as many bug fixes.
  • BatBox is a set of add-on tools for the standard LinkSys firmware
  • Folks at SeattleWireless.net document the router on their wiki and have a fascinating website about creating community wireless nets. They also highlight NoCatSplash, an “Open Public Network Gateway Daemon” in case you plan to offer a community site with a sign-on or “I Agree” click-through.
  • OpenWrt takes a different tack, offering a base distribution on top of which you can customize your own tools
  • Portless Networks offer their eWrt distribution, a fork from an earlier version of the Sveasoft software, with a goal of developing a stable distribution for ISPs and other network providers.
  • HyperWRT focuses on boosting the broadcast power, a great idea if you are not in a dense urban environment and want maximum broadcast range

So, why would you hack a working appliance just to put your own custom software on it? 1) It’s cool. 2) Bug fixes 3) More features 4) Why not?

Another convert to FireFox

Why I dumped Internet Explorer. “CNET News.com’s Charles Cooper confesses that he’s a Firefox convert and not at all nostalgic for the old days.” From CNET News.com. Great quotes from the article:

“After months waiting for Microsoft to give me a reason to remain loyal, I finally dumped Internet Explorer for the Firefox Web browser last week.”

“There is one major change you can ascribe to Internet Explorer: The PC browser world is in much worse shape. Because management took so long to tackle Internet Explorer’s security woes, Microsoft allowed virus writers to exploit vulnerabilities in the browser and wreak untold havoc on unsuspecting computer users.”

Technorati’s Lessons Learned

The Doc Searls Weblog points to an article by David Sifry, listing their cascading troubles that started with a fire at their colocation facility. I went through a similar learning experience while I was at BugCentral.com and we had our servers hosted by USDataCenters. Short answer: you should have a local UPS on your machine with ‘soft shutdown’ software in place so that your box doesn’t get corrupted when the rest of the facility goes down.

There’s a Mr. Murphy here, and he’s got a torch.
