Note: Effective October 18, 2011, Cisco moved the current list of
Cisco Security Advisories and Responses published by Cisco PSIRT. The
new location is http://tools.cisco.com/security/center/publicationListing
You can also navigate to this page from the Cisco
Products and Services menu of the Cisco Security Intelligence
Operations (SIO) Portal. Following this transition, new Cisco
Security Advisories and Responses will be published to the new
location. Although the URL has changed, the content of security
documents and the vulnerability policy are not impacted. Cisco will
continue to disclose security vulnerabilities in accordance with the
published Security Vulnerability Policy

Affected Products
=================

Vulnerable Products
+------------------

These vulnerabilities only affect 6.x versions of Cisco Security
Agent running on Windows platforms.

Products Confirmed Not Vulnerable
+--------------------------------

No software releases of Cisco Security Agent running on Linux
platforms are affected. Software releases prior to 6.0 running on
Windows platforms are not affected by these vulnerabilities.

No other Cisco products are currently known to be affected by these
vulnerabilities.

Details
=======

The Cisco Security Agent is a security software agent that provides
threat protection for server and desktop computing systems. Cisco
Security Agents can be standalone agents or can be managed by the
Cisco Security Agent Management Center.

Version 6.x of Cisco Security Agent running on Windows platforms are
affected by the following vulnerabilities:

  * Vulnerability in the Oracle Outside In Technology component in
    Oracle Fusion Middleware 8.3.5.0 allows local users to affect
    availability, related to File ID SDK.
    This vulnerability is assigned Common Vulnerabilities and
    Exposures (CVE) IDs CVE-2011-0794
  * Vulnerability in the Oracle Outside In Technology component in
    Oracle Fusion Middleware 8.3.2.0 and 8.3.5.0 allows local users
    to affect availability via vectors related to Outside In Filters.
    This vulnerability is assigned Common Vulnerabilities and
    Exposures (CVE) IDs CVE-2011-0808

These vulnerabilities are addressed and documented in Cisco bug ID 
CSCtq29413.

These vulnerabilities can be triggered during the normal operation of
Cisco Security Agent if Data Loss Prevention (DLP) policies are
enabled. The DLP policies are available only on Windows platforms.
When inspected by Cisco Security Agent, a crafted file could allow an
attacker to execute arbitrary code with Administrator privileges.

Vulnerability Scoring Details
+----------------------------

Cisco has provided scores for the vulnerabilities in this advisory
based on the Common Vulnerability Scoring System (CVSS). The CVSS
scoring in this Security Advisory is done in accordance with CVSS
version 2.0.

CVSS is a standards-based scoring method that conveys vulnerability
severity and helps determine urgency and priority of response.

Cisco has provided a base and temporal score. Customers can then
compute environmental scores to assist in determining the impact of
the vulnerability in individual networks.

Cisco has provided an FAQ to answer additional questions regarding
CVSS at:

http://www.cisco.com/web/about/security/intelligence/cvss-qandas.html

Cisco has also provided a CVSS calculator to help compute the
environmental impact for individual networks at:

http://intellishield.cisco.com/security/alertmanager/cvss

* CSCtq29413, Oracle Onenote library vulnerability in CSA

CVSS Base Score - 10
    Access Vector -            Network
    Access Complexity -        Low
    Authentication -           None
    Confidentiality Impact -   Complete
    Integrity Impact -         Complete
    Availability Impact -      Complete

CVSS Temporal Score - 8.3
    Exploitability -           Functional
    Remediation Level -        Official-Fix
    Report Confidence -        Confirmed

Impact
======

Successful exploitation of these vulnerabilities could allow an
unauthenticated attacker to perform remote code execution on the
affected device that will execute with Administrator privileges.

Software Versions and Fixes
===========================

When considering software upgrades, also consult:
http://www.cisco.com/go/psirt and any subsequent advisories to 
determine exposure and a complete upgrade solution.

In all cases, customers should exercise caution to be certain the
devices to be upgraded contain sufficient memory and that current
hardware and software configurations will continue to be supported
properly by the new release. If the information is not clear, contact
the Cisco Technical Assistance Center (TAC) or your contracted
maintenance provider for assistance. 

These vulnerabilities are corrected in Cisco Security Agent software
version 6.0.2.151.

Workarounds
===========

No workaround is available to mitigate these vulnerabilities.

Obtaining Fixed Software
========================

Cisco has released free software updates that address these
vulnerabilities. Prior to deploying software, customers should
consult their maintenance provider or check the software for feature
set compatibility and known issues specific to their environment.

Customers may only install and expect support for the feature sets
they have purchased. By installing, downloading, accessing or
otherwise using such software upgrades, customers agree to be bound
by the terms of Cisco's software license terms found at:
http://www.cisco.com/en/US/docs/general/warranty/English/EU1KEN_.html 
or as otherwise set forth at Cisco.com Downloads at:
http://www.cisco.com/public/sw-center/sw-usingswc.shtml

Do not contact psirt at cisco.com or security-alert at cisco.com for
software upgrades 

Customers with Service Contracts
================================

Customers with contracts should obtain upgraded software through
their regular update channels. For most customers, this means that
upgrades should be obtained through the Software Center on Cisco's
worldwide website at http://www.cisco.com

Customers using Third Party Support Organizations
=================================================

Customers whose Cisco products are provided or maintained through
prior or existing agreements with third-party support organizations,
such as Cisco Partners, authorized resellers, or service providers
should contact that support organization for guidance and assistance
with the appropriate course of action in regards to this advisory.

The effectiveness of any workaround or fix is dependent on specific
customer situations, such as product mix, network topology, traffic
behavior, and organizational mission. Due to the variety of affected
products and releases, customers should consult with their service
provider or support organization to ensure any applied workaround or
fix is the most appropriate for use in the intended network before it
is deployed.

Customers without Service Contracts
===================================

Customers who purchase direct from Cisco but do not hold a Cisco
service contract, and customers who purchase through third-party
vendors but are unsuccessful in obtaining fixed software through
their point of sale should acquire upgrades by contacting the Cisco
Technical Assistance Center (TAC). TAC contacts are as follows.

  * +1 800 553 2447 (toll free from within North America)
  * +1 408 526 7209 (toll call from anywhere in the world)
  * e-mail: tac at cisco.com

Customers should have their product serial number available and be
prepared to give the URL of this notice as evidence of entitlement to
a free upgrade. Free upgrades for non-contract customers must be
requested through the TAC.
