TITLE:
SupportSoft ActiveX Controls Buffer Overflow Vulnerabilities

SECUNIA ADVISORY ID:
SA24251

VERIFY ADVISORY:
http://secunia.com/advisories/24251/

CRITICAL:
Highly critical

IMPACT:
System access

WHERE:
>From remote

SOFTWARE:
SupportSoft ActiveX Controls 5.x
http://secunia.com/product/13545/
SupportSoft ActiveX Controls 6.x
http://secunia.com/product/13546/

DESCRIPTION:
Some vulnerabilities have been reported in various SupportSoft
ActiveX controls, which can be exploited by malicious people to
compromise a user's system.

The vulnerabilities are caused due to boundary errors within the
SmartIssue, RemoteAssist, and Probe ActiveX controls. These can be
exploited to cause stack-based buffer overflows via overly long
arguments passed to various methods.

Successful exploitation allows execution of arbitrary code but
requires that the user is e.g. tricked into visiting a malicious web
site.

The vulnerabilities reportedly affect versions 5.5, 5.6, and 6.x.

SOLUTION:
Apply updates.
