Intel processors are vulnerable to a new Spectre vulnerability

12 July 2018
A new variant of Spectre vulnerability was discovered in Intel processors. Security researchers Vladimir Kirianski and Karl Waldspurger shared their finding.The discovered vulnerability uses all the same features of the speculative instruction execution approach as the previously found Spectre subspecies. The latter "find" allows attackers to change function pointers and return addresses in the speculative execution mechanism. This, in turn, gives hackers the ability to redirect the data stream, making information from protected memory areas available to all sorts of malware. Simply put, the vulnerability puts all passwords, cryptographic keys, or any other sensitive information at risk. The Spectre variant described above is expected to be fixed with the next processor microcode update, which will be published before the end of the week.
