TITLE:
Internet Explorer URL Parsing Buffer Overflow Vulnerability

SECUNIA ADVISORY ID:
SA21557

VERIFY ADVISORY:
http://secunia.com/advisories/21557/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
Microsoft Internet Explorer 6.x
http://secunia.com/product/11/

DESCRIPTION:
A vulnerability has been reported in Internet Explorer, which can be
exploited by malicious people to compromise a user's system.

The vulnerability is caused due to a boundary error when processing
URLs on a website using HTTP 1.1 and compression. This can be
exploited to cause a buffer overflow via an overly long URL.

Successful exploitation allows execution of arbitrary code when a
user is e.g. tricked into visiting a malicious website.

The vulnerability affects Internet Explorer 6 SP1 on Windows 2000 and
Windows XP SP1 and was introduced by the MS06-042 patches.

SOLUTION:
The vendor recommends disabling the HTTP 1.1 protocol in Internet
Explorer (see the vendor's advisory for details).
