iOSmacOS - Out-of-Bounds Timestamp Write in IOAccelCommandQueue2::processSegmentKernelCommand()

iOSmacOS - Out-of-Bounds Timestamp Write in IOAccelCommandQueue2::processSegmentKernelCommand While investigating possible shared memory issues in AGXCommandQueue::processSegmentKernelCommand, I noticed that the size checks used to parse the IOAccelKernelCommand in...

bespoke Cell implementation allows obtaining several mutable references to the same data

The custom implementation of a Cell primitive in the affected versions of this crate does not keep track of mutable references to the underlying data. This allows obtaining several mutable references to the same object which may result in arbitrary memory corruption, most likely use-after-free. T...

CVE-2019-19197

IOCTL Handling in the kyrld.sys driver in Kyrol Internet Security 9.0.6.9 allows an attacker to achieve privilege escalation, denial-of-service, and code execution via usermode because 0x9C402401 using METHODNEITHER results in a read primitive...

CVE-2019-19197

IOCTL Handling in the kyrld.sys driver in Kyrol Internet Security 9.0.6.9 allows an attacker to achieve privilege escalation, denial-of-service, and code execution via usermode because 0x9C402401 using METHODNEITHER results in a read primitive...

CVE-2019-19197

CVE-2019-19197 relates to IOCTL handling in the kyrld.sys driver of Kyrol Internet Security 9.0.6.9. The vulnerability arises when 0x9C402401 is issued via METHOD_NEITHER, leading to a read primitive that enables local privilege escalation, denial of service, and potential code execution in userm...

Remote Code Execution

Microsoft Chakra Core is vulnerable to remote code execution RCE. The vulnerability exists because it does not handle the case where the length isn't a TaggedInt during ToInt32 conversion on non-primitive length...

Trashing the Flow of Data

Posted by Stephen Röttger In this blog post I want to present crbug.com/944062, a vulnerability in Chrome’s JavaScript compiler TurboFan that was discovered independently by Samuel saelo@ via fuzzing with fuzzilli, and by myself via manual code auditing. The bug was found in beta and was fixed...

A Go implementation of Poly1305 that makes sense

Poly1305 is a Message Authentication Code--a cryptographic primitive for authenticating a message with a shared secret key, like HMAC. Although its really a fraction of the complexity of e.g. elliptic curves, most of the implementations Ive read look decidedly like magic, mysteriously multiplying...

DEBIAN-CVE-2018-16510

An issue was discovered in Artifex Ghostscript before 9.24. Incorrect exec stack handling in the "CS" and "SC" PDF primitives could be used by remote attackers able to supply crafted PDFs to crash the interpreter or possibly have unspecified other impact...

Important: kernel

Issue Overview: An industry-wide issue was found in the way many modern microprocessor designs have implemented speculative execution of Load & Store instructions a commonly used performance optimization. It relies on the presence of a precisely-defined instruction sequence in the privileged code...

CVE-2018-1120

A flaw was found affecting the Linux kernel before version 4.17. By mmaping a FUSE-backed file onto a process's memory containing command line arguments or environment strings, an attacker can cause utilities from psutils or procps such as ps, w or any other program which makes a read call to the...

MS17-010 EternalRomance / EternalSynergy / EternalChampion SMB Remote Windows Code Execution

This module requires Metasploit: https://metasploit.com/download Current source: https://github.com/rapid7/metasploit-framework Windows XP systems that are not part of a domain default to treating all network logons as if they were Guest. This prevents SMB relay attacks from gaining administrativ...

MS17-010 EternalRomance/EternalSynergy/EternalChampion SMB Remote Windows Code Execution

This module will exploit SMB with vulnerabilities in MS17-010 to achieve a write-what-where primitive. This will then be used to overwrite the connection session information with as an Administrator session. From there, the normal psexec payload code execution is done. Exploits a type confusion...

Updated xstream packages fix security vulnerability

A vulnerability was found in XStream. Parsing a maliciously crafted file could cause the application to crash. The processed stream at unmarshalling type contains type information to recreate the formerly written objects. XStream creates therefore new instances based on these type information. Th...

CVE-2016-6891

MatrixSSL before 3.8.6 allows remote attackers to cause a denial of service out-of-bounds read via a crafted ASN.1 Bit Field primitive in an X.509 certificate...

Debian DLA-484-1 : graphicsmagick security update (ImageTragick)

Several security vulnerabilities were discovered in graphicsmagick a tool to manipulate image files. GraphicsMagick is a fork of ImageMagick and also affected by vulnerabilities collectively known as ImageTragick, that are the consequence of lack of sanitization of untrusted input. An attacker wi...
