SECUNIA ADVISORY ID:
SA21989

VERIFY ADVISORY:
http://secunia.com/advisories/21989/

CRITICAL:
Extremely critical

IMPACT:
System access

WHERE:
>From remote

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

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

The vulnerability is caused due to an error in the processing of
Vector Markup Language (VML) documents. This can be exploited by e.g.
tricking a user into viewing a malicious VML document containing an
overly long "fill" method inside a "rect" tag.

Successful exploitation allows execution of arbitrary code.

NOTE: Reportedly, this is currently being exploited in the wild.

The vulnerability has been confirmed on a fully patched system with
Internet Explorer 6.0 and Microsoft Windows XP SP2. Other versions
may also be affected.

SOLUTION:
Do not visit untrusted web sites.

Deactivating Active Scripting will prevent exploitation using the
currently known exploit.

PROVIDED AND/OR DISCOVERED BY:
Sample exploit provided by Sunbelt Software.
