HTML Help ActiveX control (Hhctrl.ocx) ships as part of Microsoft HTML Help and is designed to work with Internet Explorer to provide functionality for help systems.
|
||
|
||
A remotely exploitable issue has been reported in the WinHlp facility. The software fails to perform sufficient boundary checks of the Item parameter in the WinHlp command. This issue resides in Winhlp32.exe.
|
||
|
||
An attacker can exploit this condition by embedding a call to the vulnerable ActiveX control in a malicious webpage or HTML email. If successful, the attacker may be able to execute arbitrary code on the client system as the Internet Explorer user.
|
||
|
||
Note that Windows ships with HTML Help.
|
||
|
||
The HTML Help ActiveX control can also reportedly be used to mount denial-of-service attacks and exploit other stack- and heap-based overflows.
|
||
|
||
Tiny Personal Firewall 3.0 reportedly treats the HTML Help facility as a trusted application in the default configuration. As a result, any outgoing/back-channel connections that stem from successful exploits will not be blocked by the firewall in the default configuration. Note that this issue is reportedly not present in Tiny Personal Firewall 2.0.
