VeriSign ConfigChk ActiveX Control (VSCnfChk.dll) Buffer Overflow

medium Nessus Plugin ID 24734

Synopsis

The remote Windows host has an ActiveX control that is affected by a buffer overflow vulnerability.

Description

The ConfigChk ActiveX control, included with VeriSign's PKI product on the remote host and marked as safe for scripting, is reportedly affected by a buffer overflow vulnerability involving its 'VerCompare()' method.

If an attacker can trick a user on the affected host into visiting a specially crafted web page, this issue could be leveraged to execute arbitrary code on the host subject to the user's privileges.

Solution

Apply the vendor patch and verify that the file version of the associated 'VSCnfChk.dll' is 2.0.0.3 or later.
