Microsoft IIS contains a flaw that may allow a remote attacker to exhaust the available memory and force it to restart. The issue is due to IIS not limiting the memory available for constructing headers to be returned to a web client. If an attacker uploaded a specially crafted ASP page that returned an overly large header to the requesting client, IIS will run out of memory.

Currently, there are no known workarounds or upgrades to correct this issue. However, Microsoft has released a patch to address this vulnerability.
