IE Shines On Broken Code

mschaef writes "While reading Larry Osterman'a blog (He's a long time Microsoftie, having worked on products dating back to DOS 4.0), I ran across this BugTraq entry on web browser security. Basically, the story is that Michael Zalewski started feeding randomly malformed HTML into Microsoft Internet Explorer, Mozilla, Opera, Lynx, and Links and watching what happened. Bottom line: 'All browsers but Microsoft Internet Explorer kept crashing on a regular basis due to NULL pointer references, memory corruption, buffer overflows, sometimes memory exhaustion; taking several minutes on average to encounter a tag they couldn't parse.' If you want to try this at home, he's also provided the tools he used in the BugTraq entry."

    There's a good phrase I can use to explain this one:

    If you work in a monkey house, you expect to be pelted with shit.

    I'd love to read the article, but the page seems to contain malformed HTML...

    They didn't say that IE also started randomly installing Bonzi Buddy et al during the test, the users' credit card numbers were automagically emailed to Romania, there was an sudden increase in outbound port 25 traffic from the system, and they ended the session with about 37 momre toolbars installed then they started with.

    Thats the thing about randomness. You can never be sure.

    Tell me, Mr. Anderson, what good is a browser when you are unable to access the net?

    Yep, the first mozilla_die entry crashes Mozilla 1.8a4 for me, too. Sounds like the tests are repeatable enough. Now quick, everybody rush to file bug reports and the winners can collect their $500!
