Internet Explorer remote buffer overflow



8th Mar 2002 [SBWID-5173]
COMMAND

	Internet Explorer remote buffer overflow

SYSTEMS AFFECTED

	IE 4 and above All Outlook html enbaled reders

PROBLEM

	Microsoft [http://www.microsoft.com] said :
	

	An unchecked buffer exists in one of the functions that helps to  locate
	incompletely removed applications on the system.
	

	...
	

	A successful attack would have the affect of either causing the  Windows
	Shell to crash, or causing code to run in the user\'s context.
	

	...
	

	By default, this  is  not  remotely  exploitable.  However,  under  very
	unusual conditions, it could be exploited via a web page.
	

	This exploit was originally found  by  eeye  [http://www.eeye.com],  who
	has posted an advisory regarding this.
	

	 Sample

	 ======

	

	Install AOL Instant messenger,  aim://  is  now  a  valid  url  handler,
	deinstall AIM and type in  your  web  browser  aim://<big  buffer>  :
	microsoft shell crash.
