Short Bytes: Symantec’s automated threat analysis system, Norton Safe Web, claims that Linux kernel’s website kernel.org contains 4 threats and shows a red flag to the users. Looking at Norton’s past record, this threat detection could be just another false warning. symantec’s online malware scanner websitesafeweb.norton.com claims that kernel.org, the home to Linux kernel is […]
Allwinner’s ARM Linux kernel includes “rootmydevice” code that gives apps root. Allwinner, a Chinese system-on-a-chip company that makes the processor used in many low-cost Android tablets, set-top boxes, ARM-based PCs, and other devices, apparently shipped a version of its Linux kernel with a ridiculously easy-to-use backdoor built in. All any code needs to do to gain […]
Short Bytes: The code of Linux kernel of Chinese chipmaker Allwinner contains an easily exploitable root backdoor. Combined with networked services, this could be used to perform remote exploits on the Allwinner’s ARM processor devices. The affected devices also include popular developer boards like Orange Pi and Banana Pi. Allwinner is a Chinese company that makes […]
Sasha Levin kicks off ‘security tree’ side project. Linux developer Sasha Levin has kicked off a project in which he proposes gathering up kernel security fixes under a single tree. The rationale behind the “Linux-stable security tree project”, he explains, is that sysadmins in large, complex deployments find following kernel upgrades is daunting. “Quite a few […]
This is kind of a big deal because the mess is in 14.04 LTS, expiry date 2019. Ubuntu has patched four Linux kernel vulnerabilities that allowed for arbitrary code execution and denial of service attacjs. The flaws (CVE-2015-8812, CVE-2016-2085, CVE-2016-2550, CVE-2016-2847) is fixed in Ubuntu 14.04 LTS. Researcher Venkatesh Pottem found a use-after-free vulnerability in the […]
Android re-installation ahoy to sink privilege elevation that opens avenue for rooting apps. Google has shipped an out-of-band patch for Android shuttering a bug that is under active exploitation to root devices. The vulnerability (CVE-2015-1805) affects all Android devices running Linux kernel versions below 3.18. The vulnerability allows a privilege elevation rated critical that lets apps […]
Image | Reddit Short Bytes: Linux kernel 4.1.15, a branch of 4.1.x LTS version, is now available for download. It’s the same version that ran on Skynet’s T-800 Terminator used by Arnold Schwarzenegger. It seems, just like fossBytes, Skynet cared a lot about open source. Back in February, when Linus Torvalds announced that it was time […]
All Ubuntu users are urged to update as soon as possible. Canonical has just published four Ubuntu Security Notices that detail a recent Linux kernel vulnerability discovered in the kernel packages of all of the supported Ubuntu operating systems. It has been discovered that Linux kernel’s KVM (Kernel-based Virtual Machine) hypervisor implementation didn’t correctly caught Alignment […]
All users of the Linux 4.2 kernel must upgrade It looks like it’s still October 22 in some countries, so Greg Kroah-Hartman announced just a few minutes ago the immediate availability for download of the fourth maintenance release of Linux kernel 4.2. Looking at the appended diff from Linux kernel 4.2.3, we can notice that […]
Short Bytes: Today, we are sharing an interactive Linux Kernel map that will teach you the basics and understand the various subsystems. Take a look. The internet runs on Linux, everybody knows this fact. The Linux Kernel is one of the most complex and popular open source projects. If you wish to learn the basics, […]
Two kernel vulnerabilities were left unpatched on older devices running Android Jelly Bean and KitKat. QuarksLAB, a security research company based in Paris, France, has stumbled upon two kernel vulnerabilities in Samsung Galaxy S4 devices which Samsung has decided to patch, but only for recent devices running Android Lollipop, and not for those with Jelly Bean […]
Short Bytes: The Australian national research agency Data61 has developed an unhackable kernel named seL4 and proved its unhackable property mathematically. The kernel does this job by separating the critical systems and data from the kernel. Today, the threat of cyber attacks isn’t just limited to computers and smartphones. With the ever-increasing intrusion of computers and […]
When auditing iOS kernel executable, we found that the code quality ofcom.apple.driver.AppleHDQGasGaugeControl is very bad. In this blog, we will disclose 3 vulnerabilities in this kernel extension on the latest public iOS (version 8.4.1). More importantly, one of these bugs is a perfect heap overflow vulnerability that allows us to defeat all kernel mitigations and […]
