Intel’s ‘Virtual Fences’ Spectre Fix Won’t Protect Against Variant 4

Spectre and Meltdown fixes for Intel chips announced in March, to be embedded into new CPUs, do not address the newly disclosed Variant 4, sources said. Intel introduced hardware-based safeguards to its new chips to protect against the Spectre and Meltdown flaws that rocked the silicon industry...

CVE-2018-11319

Syntastic aka vim-syntastic through 3.9.0 does not properly handle searches for configuration files it searches the current directory up to potentially the root. This improper handling might be exploited for arbitrary code execution via a malicious gcc plugin, if an attacker has write access to a...

Excerpts from 10 Endpoint Security Problems – And How the Cloud Solves Them

Predicting new threats is the top challenge for security and IT professionals Traditional antivirus is based on what’s already known – it can only stop known malware attacks based on the signatures it has at the moment. But the problem is only 30% of attacks are malware-based; if you rely solely ...

Another Branch Prediction Attack

When Spectre and Meltdown were first announced earlier this year, pretty much everyone predicted that there would be many more attacks targeting branch prediction in microprocessors. Here's another one: In the new attack, an attacker primes the PHT and running branch instructions so that the PHT...
