CVE-2022-2274

The OpenSSL 3.0.4 release introduced a serious bug in the RSA implementation for X8664 CPUs supporting the AVX512IFMA instructions. This issue makes the RSA implementation with 2048 bit private keys incorrect on such machines and memory corruption will happen during the computation. As a...

OpenSSL to Release Security Patch for Remote Memory Corruption Vulnerability

The latest version of the OpenSSL library has been discovered as susceptible to a remote memory-corruption vulnerability on select systems. The issue has been identified in OpenSSL version 3.0.4, which was released on June 21, 2022, and impacts x64 systems with the AVX-512 instruction set. OpenSS...

Linux kernel 安全漏洞

Linux kernel is the kernel used by Linux, the open source operating system of the Linux Foundation in the United States. Linux kernel has a security vulnerability that can be exploited by an attacker to run code through the MIPS CBPF JIT compiler branch instruction...

CVE-2021-1104

The CVE-2021-1104 entry relates to the RISC-V Instruction Set Manual, where an ambiguity in the Machine Trap Vector Base Address (MTVEC) register’s initial state is not defined. This ambiguity is stated to potentially enable information disclosure, data tampering, and denial of service. The conso...

Fuzzing iOS code on macOS at native speed

Or how iOS apps on macOS work under the hood Posted by Samuel Groß, Project Zero This short post explains how code compiled for iOS can be run natively on Apple Silicon Macs. With the introduction of Apple Silicon Macs, Apple also made it possible to run iOS apps natively on these Macs. This is...

Examining Pointer Authentication on the iPhone XS

Posted by Brandon Azad, Project Zero In this post I examine Apple's implementation of Pointer Authentication on the A12 SoC used in the iPhone XS, with a focus on how Apple has improved over the ARM standard. I then demonstrate a way to use an arbitrary kernel read/write primitive to forge kernel...

Router exploitation of the Stack Overflow entry a-vulnerability warning-the black bar safety net

MIPS instruction set is mainly used in some embedded IOT devices, such as Router, camera. To these devices for binary vulnerability mining you need to have the MIPS to have a certain familiar. The MIPS instruction set of Stack Overflow and the x86 instruction set is different, so the exploits is...

Rosenbridge - Hardware Backdoors In Some X86 CPUs

project:rosenbridge reveals a hardware backdoor in some desktop, laptop, and embedded x86 processors. The backdoor allows ring 3 userland code to circumvent processor protections to freely read and write ring 0 kernel data. While the backdoor is typically disabled requiring ring 0 execution to...

Reverse Engineering Cross Platform Disassembler: Panopticon

Reverse Engineering Cross Platform Disassembler Panopticon is a disassembler that understands the semantics of opcodes. This way it’s able to help the user by discovering and displaying invariants that would have to be discovered “by hand” in traditional disassemblers. This allows an interactive...

Kernel: crypto: buffer overruns in RFC4106 implementation using AESNI

A buffer overflow flaw was found in the way the Linux kernel's Intel AES-NI instructions optimized version of the RFC4106 GCM mode decryption functionality handled fragmented packets. A remote attacker could use this flaw to crash, or potentially escalate their privileges on, a system over a...
