Cybersecurity researchers have disclosed  two unpatched security vulnerabilities  in the open-source U-Boot boot loader. The issues, which were uncovered in the  IP defragmentation  algorithm implemented in U-Boot by NCC Group, could be abused to achieve arbitrary out-of-bounds write and denial-of-service (DoS). U-Boot is a  boot loader  used in Linux-based embedded systems such as ChromeOS as well as ebook readers such as Amazon Kindle and Kobo eReader. The issues are summarized below - CVE-2022-30790  (CVSS score: 9.6) - Hole Descriptor overwrite in U-Boot IP packet defragmentation leads to an arbitrary out-of-bounds write primitive. CVE-2022-30552  (CVSS score: 7.1) - Large buffer overflow leads to DoS in U-Boot IP packet defragmentation code It's worth noting that both the flaws are exploitable only from the local network. But doing so can enable an attacker to root the devices and lead to a DoS by crafting a malformed packet. The shortcomings are expected to be addr

A team of cybersecurity researchers today disclosed details of a new high-risk vulnerability affecting billions of devices worldwide—including servers and workstations, laptops, desktops, and IoT systems running nearly any Linux distribution or Windows system. Dubbed ' BootHole ' and tracked as CVE-2020-10713 , the reported vulnerability resides in the GRUB2 bootloader, which, if exploited, could potentially let attackers bypass the Secure Boot feature and gain high-privileged persistent and stealthy access to the targeted systems. Secure Boot is a security feature of the Unified Extensible Firmware Interface (UEFI) that uses a bootloader to load critical components, peripherals, and the operating system while ensuring that only cryptographically signed code executes during the boot process. "One of the explicit design goals of Secure Boot is to prevent unauthorized code, even running with administrator privileges, from gaining additional privileges and pre-OS pers

The introduction of Open AI's ChatGPT was a defining moment for the software industry, touching off a GenAI race with its November 2022 release. SaaS vendors are now rushing to upgrade tools with enhanced productivity capabilities that are driven by generative AI. Among a wide range of uses, GenAI tools make it easier for developers to build software, assist sales teams in mundane email writing, help marketers produce unique content at low cost, and enable teams and creatives to brainstorm new ideas.  Recent significant GenAI product launches include Microsoft 365 Copilot, GitHub Copilot, and Salesforce Einstein GPT. Notably, these GenAI tools from leading SaaS providers are paid enhancements, a clear sign that no SaaS provider will want to miss out on cashing in on the GenAI transformation. Google will soon launch its SGE "Search Generative Experience" platform for premium AI-generated summaries rather than a list of websites.  At this pace, it's just a matter of a short time befo

Security researchers have discovered several severe zero-day vulnerabilities in the mobile bootloaders from at least four popular device manufacturers that could allow an attacker to gain persistent root access on the device. A team of nine security researchers from the University of California Santa Barbara created a special static binary tool called BootStomp that automatically detects security vulnerabilities in bootloaders. Since bootloaders are usually closed source and hard to reverse-engineer, performing analysis on them is difficult, especially because hardware dependencies hinder dynamic analysis. Therefore, the researchers created BootStomp, which "uses a novel combination of static analysis techniques and underconstrained symbolic execution to build a multi-tag taint analysis capable of identifying bootloader vulnerabilities." The tool helped the researchers discover six previously-unknown critical security bugs across bootloaders from HiSilicon (Huawe
