"IE5 Weirdness #1: The FavIcon Mystery (and Security Hole)

Reader Brian Dillree was the first of several readers to ask
a question about an increasingly common practice:

Fred,
I'm hoping you can help me on this one.It
has me and a couple other people stumped.
How do some websites insert their own icon
into ie5 internet shorcuts?
If you don't know what I mean, go to
deja.com (for example) and create a shortcut to it
either on your desktop or right in the ie5 toolbar
and the standard ie5 icon is replaced with the
deja.com icon.
How is this possible??
Thanx in advance
Brian Dillree

If a web designer creates a special icon for a web page,
makes it 16x16 pixels in size, uses 16 colors, and names it
"favicon.ico," then when you either put that page on your
favorites list or create a shortcut on your desktop, IE5
will use the "favicon" icon in place of the standard dog-
eared web page IE5 icon.

Lots of web sites are doing this now as a way to customize
their look and to help make their pages stand out from the
crowd.

But there can be a problem: As Microsoft puts it, "A
specially-malformed icon could overrun the buffer and be
used to run arbitrary code on the user's computer." By which
they mean someone could hack your system and run whatever
software they wanted.

About 60 days ago, Microsoft released a patch for this
"vulnerability;" If you've been keeping up with all your
updates and fixes, you probably already have this one. But
if not--- check out
microsoft.com

But there's another snag: It's theoretically possible for a
web site to track which IP address is calling for the
favicon.ico. This isn't exactly a gaping security hole, but
it is at least theoretically possible for a site owner to
figure out which IP addresses are bookmarking his or her
site. It would be somewhat easier for the site to build a
log of your bookmarks if you let the site set a cookie, or
if you registered upon entry.

I mention low-risk security hole this in the interests of
completeness, but I also have to say I think the odds of
anyone going to that amount of hassle just to see if you
bookmarked a page on their site are quite remote. And even
if they did know what you bookmarked from their site, so
what?

Note that there's no way for a favicon to be used to snoop
your other bookmarks, or to see what you bookmark on other
sites.

So this is a mostly theoretical problem--- and a tiny one at
that.

But the "malformed favicon" issue is more real--- grab the
patch, if you haven't already."

"IE5 Weirdness #2: Bogus "AutoComplete/AutoFill" Entries

A lot of people have been bugged by Internet Explorer 5's
"AutoComplete/AutoFill" feature (which appeared in a more
limited form in IE4). The AutoComplete feature opens a
little text box as you type a URL or fill out a web form,
and suggests possible matches from past entries you've made.

Trouble is, it remembers your mistakes too. I filled out a
form once using fred@langa.cpm instead of fred@langa.com,
but IE5 remembered my error forever, offering the bogus
".cpm" version of my email address every time I tried to
enter my real address.

And I know I'm not alone---I've gotten a lot of mail asking
how to clear out bogus entries. Take this note from reader
John Quist:

Hi Fred!
Great job, love your letters and website.
But I have a question, is there anyway to clean
out the history on the searches on IE5? And the
AutoFill feature has some undesirable places and
things trapped in it. I've cleaned out the history
folder and set it to expire after 1 day, and I've
cleaned out the Temporary Files. But nothing I've
tried will clean out the searches that were done
in the past.. Any suggestions?
A thoroughly happy subscriber.--- John

Turns out it's easy. To clear out bad form entries:

1. In IE5, click to Tools/Internet
Options/Content/AutoComplete.
2. You have two choices. You can "Clear Forms" or "Clear
Passwords." This is a good thing because the bogus entries
are unlikely to be valid name/password combinations; you can
clear out the garbage without deleting any saved passwords.

For bad web addresses, it's very similar:

1. Click to Tools/Internet Options/General
2. Click Clear History

If all you want to do is clear out one or two bad entries,
it's even easier: When you see an AutoComplete entry you
wish wasn't on your list, click on the bogus item and then
press the DELETE key."
