Researchers have exposed new and sophisticated types of attacks that endanger the security and confidentiality of virtual machines (VMs). Two variations of Ahoi attacks, Heckler and WeSee, have been identified targeting hardware-based trusted execution environments, specifically AMD’s Secure Encrypted Virtualization-Secure Nested Paging (SEV-SNP) and Intel’s Trust Domain Extensions (TDX) technologies.
The recently uncovered "Native Branch History Injection (BHI)" exploit against the Linux kernel marks a significant milestone in the ongoing battle against Spectre v2 vulnerabilities. Researchers have revealed that BHI can bypass existing Spectre v2/BHI mitigations to read sensitive data from the memory of Intel systems.
A significant security threat, known as the Spectre v2 exploit, has been observed targeting Linux systems running on modern Intel processors. Let's delve into the details of the Spectre v2 exploit, its implications, and the measures being taken to mitigate its impact.
Linux admins and security practitioners face significant challenges in keeping their Linux systems secure amidst the constant threat of kernel bugs. Understanding and mitigating the vulnerabilities in the Linux kernel is essential in safeguarding your systems against exploits leading to compromise. Let's examine why kernel vulnerabilities are such a severe threat and mitigation strategies for protecting against them.
Several significant vulnerabilities have been found in the Thunderbird email client and Firefox web browser. An attacker could exploit these issues to disrupt services, obtain sensitive data, bypass security restrictions, perform cross-site tracing, run rogue programs on your computer, or escalate privileges on impacted systems.
