CVE reference:	CVE-2004-0212

Description: Microsoft has issued an update for Windows. This fixes a vulnerability, allowing malicious websites to execute arbitrary code on a vulnerable system. The vulnerability is caused due a boundary error within the Task Scheduler ("mstask.dll") when handling the "to be executed" field of ".job" files. This can be exploited to cause a stack-based buffer overflow when a folder containing a malicious ".job" file is viewed (e.g. by tricking a user into visiting a malicious website with a frame pointing to an anonymous share containing a specially crafted ".job" file). The vulnerability affects Microsoft Windows 2000 and Windows XP. Microsoft Windows NT 4 is also affected if Internet Explorer 6 SP1 is installed. Solution: Microsoft has released updates.
