ARM Holdings estimated that around 5 per cent of more than 120 billion chips its partners have shipped since 1991 was impacted by Spectre. Internet and networking equipment maker Cisco Systems said in a security advisory that it has identified 18 vulnerable products, including some of its blade servers, rack servers and routers, and expects to have patches for servers in about five weeks.Apple also released an updated version of its operating system software to fix the security flaw.The memory corruption flaws, named Meltdown and Spectre, could allow hackers to bypass China silicone rubber Manufacturers operating systems and other security software to steal passwords or encryption keys on most types of computers, phones and cloud-based servers.

Microsoft also said that security updates froze some computers using chipsets from Intel rival AMD, dragging AMD’s shares down nearly 4 per cent. AMD said it was aware of an issue with some older-generation processors following the installation of a Microsoft security update that was published over the weekend. The majority of Cisco’s products were not vulnerable because they are “closed systems that do not allow customers to run custom code on the device,” it said.5 per cent taking the loss since the issue surfaced last week to about 7 per cent or around 15 billion in market value.

AMD shares have gained nearly 20 per cent in the last week as investors speculated that the chipmaker could wrest market share from Intel, whose chips were most exposed to the security flaws. “ARM will address Spectre in future processors but there will need to be an ongoing discipline in the design of secure systems which needs to be addressed through both software and hardware,” a company spokesman said in an emailed statement. Security researchers disclosed the flaws that affected nearly every computing device containing chips from Intel, AMD and ARM Holdings Microsoft said it was working with AMD to resolve the issues. The chipmaker said that fixes for security issues in its microchips would not slow down computers, rebuffing concerns that the flaws would significantly reduce performance.. Shares in Intel, which reiterated on Tuesday that it saw no sign of a significant slowdown in computers, fell 2. Intel and AMD have not disclosed the number of chips affected by the security flaws.Intel said a typical home and business PC user should not see significant slowdowns in common tasks such as reading email, writing a document or accessing digital photos. It said the number of chips affected by Meltdown was significantly less. "We (and others in the industry) had learned of this vulnerability under nondisclosure agreement several months ago and immediately began developing engineering mitigations and updating our cloud infrastructure," Microsoft executive Terry Myerson wrote in a blog post. Cisco said it is also looking for problems in nearly 30 other products, including switches and routers.
