SPECS

Processor implementation errata remain a problem, and worse, a subset of these bugs are security-critical. We classified 7 years of errata from recent commercial processors to understand the magnitude and severity of this problem, and found that of 301 errata analyzed, 28 are security-critical. We propose the SECURITY-CRITICAL PROCESSOR ER- RATA CATCHING SYSTEM (SPECS) as a low-overhead solution to this problem. SPECS employs a dynamic...
