These vulnerabilities are in a third-party library (Oracle Outside In) and are documented in CERT-CC Vulnerability Note VU#520721 at http://www.kb.cert.org/vuls/id/520721 Cisco has released free software updates that address this vulnerability. No workaround is available to mitigate these vulnerabilities. This advisory is posted at: http://tools.cisco.com/security/center/content/CiscoSecurityAdvisory/cisco-sa-20111026-csa 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@cisco.com or security-alert@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@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. Refer to http://www.cisco.com/en/US/support/tsd_cisco_worldwide_contacts.html for additional TAC contact information, including localized telephone numbers, and instructions and e-mail addresses for use in various languages.
