G Suite and Google Cloud platforms have been updated to protect against known attacks, the company said, though it acknowledged concerns that a variant of Spectre is considered more difficult to defend against. Microsoft and others in the industry were notified of the issue several months ago under a nondisclosure agreement, Terry Myerson, executive vice president of Microsoft's Windows and Devices group, noted earlier this week in an online post. The company immediately began engineering work on updates to mitigate the risk. The flaw could allow a nonprivileged user to access passwords or secret keys on a computer or a multitenant cloud server, explained Stratechery analyst Ben Thompson in a post Myerson referenced. Contrary to Intel's protests, the potential risk from Meltdown is due to a design flaw, Thompson also noted. Users of Windows 8 or Windows 7 systems using Haswell or older CPUs and would see a decrease in system performance after patching the flaw, Myerson noted. Apple released updates for iOS, macOS High Sierra, and Safari on Sierra and El Capitan, noting the issue relates to all modern processors and affects nearly all computers and operating systems. However there have been no reported compromises of customer data, Apple added, and Apple Watch is not affected by Meltdown or Spectre. Performance Over Prudence "The Meltdown and Spectre vulnerabilities require adjustment to critical, low-level interfaces in affected operating systems," said Mark Nunnikhoven, vice president of cloud security at Trend Micro. "Given the scale of the issue, the patches by Microsoft, Apple, Google and others have been very successful," he told TechNewsWorld. Still, there have been problems in some cases, Nunnikhoven said, noting that Microsoft and AMD have been pointing fingers at one another following reports of computers slowing down or in some cases not booting. Microsoft has suspended automatic updates and is working with AMD on a solution, it said in a security bulletin. Like most organizations, chip manufacturers long have prioritized speed over security," said Ryan Kalember, senior vice president of cybersecurity strategy at Proofpoint, "and that has led to a tremendous amount of sensitive data being placed at risk of unauthorized access via Meltdown and Spectre. The software patch required to fix Meltdown can slow computer processors down by as much as 30 percent, said Alton Kizziah, vice president of global managed services at Kudelski Security. "Organizations need to test patches before installing them to make sure that systems that may already be pushed to their limits won't crash and cease functioning as a result of the patch," he told TechNewsWorld. Also, those using Microsoft patches may need to make adjustments to their registry keys to avoid interference with antivirus software
