What HTTP exploit?

It seems to be another stupid Microsoft Exploit that just
causes annoyance for Unix Boxes.
The only side effect is they fill my dmesg logs with
signal 11's from apache crashing.

   Am I the only one that sees the irony that Apache seg faults from an
attack aimed at Msoft?!

I mentioned that too to the original poster, but they didn't seem that concerned since Apache respawns itself. I thought if it can be crashed by cramming too much info into a buffer before it's truncated, that's considered a buffer overflow. I'm no programmer and may be off base here but it just struck me as odd also. You're not alone Mike. :slight_smile:

it could also be a heap overflow (unless we are talking fbsd, for example).
regardless, i would be very interested in having a look at that gentleman's
apache setup to see if we can crash it reliably <g>

The real irony is that it doesn’t bother Apache running on NT :slight_smile:

In all fairness, somewhere along the line there was a patch for this. All my Apache servers do is put “request failed: URI too long” in the error log. Even without the fix it really wasn’t anything more than a nuisance. Killing off one child process had no effect on valid sessions or the parent process.

This also has no effect on Apache 1.3.28 on OpenBSD 3.4 (-stable), other than logging an extremely long request string. Of course, the OpenBSD folks audit/patch their own version of Apache, so it might have the patch you mention.
