To safeguard its customers from potential security bugs in chips, Google has deployed a novel chip-level patch across its entire infrastructure, resulting in only minor declines in performance in most cases.\u201cIn response to the vulnerabilities that were discovered, we developed a novel mitigation called \u2018Retpoline\u2019\u2014a binary modification technique that protects against \u2018branch target injection\u2019 attacks,\u201d Matt Linton, Senior Security Engineer and Pat Parseghian, Technical Programme Manager at Google wrote in a joint blog post on Thursday.<\/p>\n
\u201cWe shared \u2018Retpoline\u2019 with our industry partners and have deployed it on Google\u2019s systems, where we have observed negligible impact on performance,\u201d the engineers added.<\/p>\n
In addition, the tech giant has deployed \u201cKernel Page Table Isolation\u201d (KPTI) which is a general purpose technique for better protecting sensitive information in memory from other software running on a machine.<\/p>\n
\u201cKPTI\u201d has been deployed to the entire fleet of Google Linux production servers that support all of our products, including Search, Gmail, YouTube and Google Cloud Platform, the company said in a statement.<\/p>\n
Earlier, Intel had confirmed serious security flaws in modern processors that could affect its computers released in the last two decades.<\/p>\n
The chip-maker had said that the bug, if used for malicious purposes, has the potential to improperly gather sensitive data from computing devices and promised to fix the bug as soon as possible.<\/p>\n
It added that the vulnerability, discovered by a British tech website, the Register, is not unique to Intel products.<\/p>\n
It argued that \u201cmany types of computing devices\u2014with many different vendors\u2019 processors and operating systems\u2014are susceptible to these exploits\u201d.<\/p>\n
Software major Microsoft has already issued emergency updates to supported versions of Windows that was part of a number of fixes that would protect against the processor bug in Intel as well as AMD and ARM CPUs.<\/p>\n
Amazon was also reportedly working on security updates to their Cloud services and other products.<\/p>\n
