- The flaw can be even more dangerous than the infamous Spectre vulnerability.
- The ‘SPOILER’ flaw takes advantage of speculative execution in order to reveal memory layout data.
Experts have warned about a new major security vulnerability that impacts all Intel processors. Identified as ‘SPOILER’, the flaw can be even more dangerous than the infamous Spectre vulnerability.
What is SPOILER - SPOILER was detected by researchers at Worcester Polytechnic Institute in Massachusetts and the University of Lübeck in Germany. The new flaw bears some similarities to Spectre attacks were revealed last year. However, the team notes that “Spoiler is not a Spectre attack."
“The root cause of the issue is that the memory operations execute speculatively and the processor resolves the dependency when the full physical address bits are available,” said Ahmad Moghimi, one of the researchers in the research paper.
Intel was aware of it - Intel was informed of the findings in early December. However, it did not respond immediately. The company believes that such issues can be addressed by employing side channel safe software. Such software will avoid control flows that are dependent on the data of interest, Techradar reported.
