Vulnerability is a cyber-security term that refers to a flaw in a system that can leave it open to attack. It is may also refer to any type of weakness in a computer system itself, in a set of procedures, or in anything that leaves information security exposed to a threat.
Computer users and network personnel can protect computer systems from vulnerabilities by keeping software security patches up to date. These patches can remedy flaws or security holes that were found in the initial release. Computer and network personnel should also stay informed about current vulnerabilities in the software they use and seek out ways to protect against them.
Spectre Next Generation: New Intel CPU Vulnerabilities Found
Following January’s reports of Meltdown and Spectre affecting Intel processors, security researchers found eight new vulnerabilities in Intel processors. As Google Project Zero’s 90-day deadline ends on May 7 for companies’ disclosure of technical details and solutions, the flaws — named Spectre Next Generation or Spectre NG — were characterized as similar to the previous Spectre attack scenarios. Four of the flaws were rated as “high” risk and the rest are of “medium” severity.
Each vulnerability will have their own number in the Common Vulnerability Enumerator (CVE) directory. Intel patches will come in two waves, with one in May and the next in August. Linux developers are working on measures against Spectre as well, while Microsoft is preparing patches for the said vulnerabilities, which they will distribute as optional updates. Further, Microsoft is also offering $250,000 in a bug bounty program for more unknown Spectre-related flaws. Advanced RISC Machine (ARM) CPUs from Japan’s Softbank’s ARM Holdings are speculated to also be affected by these new vulnerabilities, while Advanced Micro Devices’ (AMD) architecture is still being examined.
New information suggested that Intel requested to postpone the publishing of the vulnerabilities’ technical details, and it seems that Google Project Zero agreed to the delay. Due to the number of affected systems, the company is seen having problems getting the patches out in time for May 7 and intends to do the coordinated release of the microcodes on May 21 or July 10 with the details of at least two variants. Likely affected systems include Core processors, Xeon spinoffs, Atom-based Pentium, Atom and Celeron CPUs released since 2013, which affects desktops, laptops, smartphones and other embedded devices. The August 14 patch will likely address the most serious vulnerability affecting cloud environments, and Intel is reportedly releasing hardware and software improvements for other manufacturers and vendors to implement.
