Researchers at the University of Virginia School of Engineering computer science department have discovered vulnerabilities earlier in the speculative execution chain of a processor than the Spectre flaw which was made public in January 2018.
A French researcher claims to have found a working exploit for the Spectre vulnerability on Linux systems on the VirusTotal database, the first such exploit to come to light since the flaw was made public by Intel back in 2018.
The OpenSSH project has implemented changes in its implementation of secure shell to guard against speculative execution and memory side-channel attacks — Spectre, Meltdown, Rowhammer and RAMBleed — developer Damien Miller says.
Intel has revealed four more vulnerabilities in all its modern processors, all of which could lead to side channel attacks that use speculative execution to leak data.
The head of the OpenBSD project, Theo de Raadt, has warned that more flaws related to speculative execution in Intel CPUs are likely to be found and that the two vulnerabilities found by Intel, as a result of examining the Foreshadow bug — found by two independent teams — are cause for much worry.
Intel has released details of three more vulnerabilities in its Core and Xeon processor lines, all of which involve exploiting the feature known as speculative execution where processors attempt to anticipate and execute instructions.
The OpenBSD project, which produces an UNIX-like operating system of the same name, has decided to disable support for hyperthreading for Intel processors as it could lead to data leaks in a manner similar to that caused by the Spectre flaws in Intel processors announced earlier this year.
Intel has revealed details of yet another vulnerability in its Core-based processor line, an information leak caused by speculative execution that affects operating systems which use lazy FPU context switching.
Two new variants of the processor vulnerability known as Spectre, that was announced in January, have been announced by Google and Microsoft.
Serious security flaws caused by "speculative execution" have been found in Intel CPUs from the Pentium Pro onwards, with multiple research teams being credited with the discoveries.
