-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ESA-2011-036: RSA, The Security Division of EMC, announces the release of a Security Fix for RSA® Adaptive Authentication (On-Premise) Advisories Updated December 6, 2011 Summary: An issue with RSA® Adaptive Authentication (On-Premise) was discovered which in certain circumstances might affect the Device Recovery capability and Device Identification used by the defined policy. Description: CVE Identifiers: CVE-2011-2741, CVE-2011-2742 In certain circumstances the accuracy of the Device Recovery capability and Device Identification used by the defined policy might be affected by the data elements sent from the end user’s device. This Security Fix provides remediation for items that cause this behavior through product fixes, as well as configuration and policy changes. More information on each of these items is included below. RSA has identified and addressed the potential security flaws as part of this Security Fix: •In certain circumstances, device recovery capabilities and device identification used by the defined policy may be impacted by the data elements sent from the end user’s device. This may potentially allow the system to recover a previously non-registered device or allow access for a registered device despite forensic differences. This potential flaw affects both web and mobile browsers. CVE (Common Vulnerability Enumeration) ID for this issue CVE-2011-2741. •In certain circumstances, the application may match device tokens sent from mobile apps without proper forensic evaluation used by the defined policy. This may potentially allow access from the mobile device to the protected application without a challenge. This potential flaw only affects mobile apps and does not affect web browsers. CVE (Common Vulnerability Enumeration) ID for this issue CVE-2011-2742. In addition, the Security Fix provides better capabilities to differentiate between activities originating from web browsers, mobile browsers, and mobile apps. This also allows customers to enable / disable the Device Recovery for each. Due to forensic similarities between browsers across mobile devices, RSA recommends that customers use these capabilities to disable device recovery specifically for mobile browsers. Note: Due to the nature of above changes, deployment of this Security Fix may have an impact on existing challenge rates. As with any other Security Fix, RSA recommends that customers fully test the fix before going into production.
