![]() ![]() ![]() ![]() ![]() Check the software repositories of ask your OS vendor if they released these important updates that mitigate the two variants of the Spectre vulnerability, which is harder to fix than Meltdown. You should also make sure you have the latest microcode firmware update for your Intel or AMD processor installed on your personal computer. Check out the GIF below to see Jerry Bezencon's script in action, and remember to update your system, if it's still vulnerable, by installing all the latest software and kernel updates. With a simple double mouse click on the sm-start script, you'll be able to see if your Linux PC is protected or not against Meltdown and Spectre vulnerabilities. Speculative execution side channel exploits do not modify memory but attempt to infer privileged data in the memory. Linux Lite 6.6 RC1 Released - Support for 22 Languages Added - See Release Announcement Section. Spectre is a class of side channel attacks that exploit branch prediction and speculative execution on modern CPUs to read memory, possibly bypassing access controls. If you don't want to go to Stéphane Lesimple's GitHub page and download the latest version of the spectre-meltdown-checker script to check if your Linux PC is vulnerable to Meltdown and Spectre attacks, you can instead download Jerry Bezencon's script, make it executable with the " chmod +x sm-*" command and run it. Linux Lite Forums - Results for meltdown and spectre. Here's how to use it to check if your distro is vulnerable or not Jerry Bezencon, the creator of the Linux Lite distribution, decided to make it easy for users to use the spectre-meltdown-checker script by creating another script that automatically downloads the latest version of Stéphane Lesimple's script and runs it on their specific GNU/Linux distro. Sandboxie uses the motto: "Trust no program".The developer of the Ubuntu-based Linux Lite distribution has created a script that makes it easier for Linux users to check if their systems are vulnerable to the Meltdown and Spectre security flaws.Īs we reported last week, developer Stéphane Lesimple created an excellent script that would check if your Linux distribution's kernel is patched against the Meltdown and Spectre security vulnerabilities that have been publicly disclosed earlier this month and put billions of devices at risk of attacks. Still, it's out there and the tech security industry believes there will more exploits against hardware, at least the cpu, in coming years. I do agree it's not as bad as the media has made it seem with its sensationalizing of the exploit. Firefox, I believe, has a similar option available. Chrome beta already has the site isolation flag which defends against the exploit nearly 100%. That said, browser vendors will no doubt patch their products to defend against it. Spectre is also capable of bypassing ALSR, so it could potentially exploit browser vulnerabilities as well. Meltdown-RW was initially erroneously labeled Spectre Variant 1.2, though because the cause of transient execution is a page-fault exception, the correct classification of this vulnerability. The concern is that user's login tokens could be stolen from one open tab via another tab opened running malicious javascript. True it may not be as reliable an exploit as Meltdown, but it is (or certainly will be) capable of being used to remotely exploit browsers using malicious javascript embedded in, for example, an advertisement. ![]()
