Advisories
Updated December 12, 2011


Summary:

RSA, The Security Division of EMC, announces security fixes and improvements for RSA SecurID Software Token 4.1 for Microsoft Windows
This release addresses an Insecure Library Loading vulnerability within RSA SecurID Software Token for Windows (CVE-2011-4141).
This release also provides an alternate installation package for customers who do not require the software token automation API features of the product.
Further information about these resolutions can be found in the RSA SecurID Software Token 4.1 for Microsoft Windows Release Notes.



Platforms:

Windows 7 Enterprise SP1 32-bit and 64-bit
Windows 7 Professional SP1 32-bit and 64-bit

Description:

This release addresses an Insecure Library Loading vulnerability within RSA SecurID Software Token for Windows (CVE-2011-4141). This vulnerability may be exploited to load arbitrary libraries by tricking a user into opening a Software Token file located on a compromised or malicious share.
The software token automation API enables integration with leading VPN and remote access applications so that users are only required to enter their usernames and SecurID PINs for authentication. This release provides an alternative installation package for customers who do not require the software token automation API features.
Support for backwards compatibility is provided by a separate installation package that installs the software token automation API. Both versions of the application will be available for direct download from rsa.com.


Further information about these resolutions can be found in the RSA SecurID Software Token 4.1 for Microsoft Windows Release Notes.



Affected Products:

RSA SecurID® Software Token 4.1 for Microsoft® Windows®



Recommendation:

RSA strongly recommends that customers upgrade to RSA SecurID Software Token 4.1.1 for Microsoft Windows.
If customers direct their end-users to download the application directly from rsa.com, they should update their instructions to ensure users download the correct version of the application.
