Potential for Signature Integrity Compromise and HMAC secret recovery in Intel® Integrated Performance Primitives (Intel® IPP) Cryptography Domain
| Intel ID: | INTEL-SA-00034 |
|---|---|
| Product family: | The cryptography (CP) domain in Intel® Integrated Performance Primitives (Intel® IPP) |
| Impact of vulnerability: | Information Disclosure |
| Severity rating: | Moderate |
| Original release: | Oct 29, 2012 |
| Last revised: | Oct 29, 2012 |
Summary:
The cryptography (CP) domain in Intel’s newest version of Intel® Integrated Performance Primitives (Intel® IPP) v7.1.1 has been enhanced to improve its security and customers are strongly urged to update to this release.
Description:
Intel IPP v7.1.1 introduces Intel® AVX & Intel® AVX2 performance optimizations for faster floating-point and integer operations in the signal processing and image processing domains. Additional
Security Improvements have been made to the CP domain’s Triple DES, AES and HMAC implementations. Customers can get these security improvements by linking with version 7.1.1 of Intel® IPP. For additional information on performance impact to Triple DES, please see the Recommendations below.
Affected products:
The cryptography (CP) domain in Intel® Integrated Performance Primitives (Intel® IPP) versions prior to 7.1.1
Recommendations:
Customers are strongly urged to update to version 7.1.1 which can be obtained from this URL: http://software.intel.com/en-us/articles/download-ipp-cryptography-libraries/
The Triple DES implementation in IPP 7.1.1 mitigates a previously identified potential vulnerability [and is more secure than prior versions], however, that resulted in some performance reduction, ranging between 35% and 70%. At this time there is no known mitigation for this performance impact in Triple DES.
