Microsoft and Redhat have released advisories regarding a new variant of the Spectre Variant 1 side-channel vulnerability that affects modern Intel CPUs which leverage speculative-execution. There is some reason to believe that it affects some AMD processors as well. But no firm information has been provided as of yet.
A vulnerability in Intel’s Active Management Technology (AMT) feature of Intel processors appears relatively easy to abusive. A remote control authentication screen can be bypassed using a blank string through a proxy server. AMT lets sysadmins perform powerful tasks over a remote connection.
