- --------------------------BEGIN INCLUDED TEXT--------------------
iDefense Security Advisory 04.02.08
http://labs.idefense.com/intelligence/vulnerabilities/
Apr 02, 2008
I. BACKGROUND
Norton Internet Security 2008 is a system security suite that offers
protection from spyware, viruses, identity theft, spam, and malicious
network traffic. More information can be found on the vendor's site at
the following URL.
http://www.symantec.com/home_homeoffice/products/overview.jsp?pcid=is&pvid=nis2008
II. DESCRIPTION
Remote exploitation of a buffer overflow vulnerability in an ActiveX
control installed by Symantec Norton Internet Security 2008 could allow
for the execution of arbitrary code.
Norton Internet Security 2008 installs the following ActiveX control
which is registered as safe for scripting:
Clsid: 3451DEDE-631F-421c-8127-FD793AFC6CC8
File: C:\PROGRA~1\COMMON~1\SYMANT~1\SUPPOR~1\SymAData.dll
Version 2.7.0.1
This control contains an exploitable stack based buffer overflow.
III. ANALYSIS
Exploitation allows attackers to execute arbitrary code with the
privileges of the currently logged in user. In order for exploitation
to occur, an attacker would have to lure a vulnerable user to a
malicious web site.
While this control is marked as safe for scripting, the control has been
designed so that it can only be run from the "symantec.com" domain. In
practice this requirement can be bypassed through the use of any Cross
Site Scripting (XSS) vulnerabilities in the Symantec domain.
Exploitation could also occur through the use of DNS poisoning attacks.
IV. DETECTION
iDefense confirmed that this vulnerability exists in version 2.7.0.1 of
the control that is installed with the 2008 version of Norton Internet
Security. Other versions may also be available.
V. WORKAROUND
Setting the kill-bit for this control will prevent it from being loaded
within Internet Explorer. However, doing so will prevent legitimate use
of the control.
VI. VENDOR RESPONSE
Symantec has addressed this vulnerability by releasing updates. For more
information, refer to their advisory at the following URL.
http://www.symantec.com/avcenter/security/Content/2008.04.02a.html
VII. CVE INFORMATION
The Common Vulnerabilities and Exposures (CVE) project has assigned the
name CVE-2008-0312 to this issue. This is a candidate for inclusion in
the CVE list (http://cve.mitre.org/), which standardizes names for
security problems.
