A use-after-free issue exists in Chrome 100 and earlier versions. A malicious extension can achieve arbitrary code execution in the browser process.

IpMatcher versions 1.0.4.1 and below for .NET Core 2.0 and .NET Framework 4.5.2 incorrectly validates octal and hexadecimal input data which can lead to indeterminate server-side request forgery, local file inclusion, remote file inclusion, and denial of service vectors.

Conti ransomware looks for and executes DLLs in its current directory. Therefore, we can potentially hijack a DLL to execute our own code and control and terminate the malware pre-encryption. The exploit dll will check if the current directory is "C:\Windows\System32" and if not we grab our process ID and terminate. We do not need to rely on hash signatures or third-party products as the malware's own flaw will do the work for us. Endpoint protection systems and or antivirus can potentially be killed prior to executing malware, but this method cannot as there's nothing to kill the DLL that just lives on disk waiting. From a defensive perspective you can add the DLLs to a specific network share containing important data as a layered approach. All basic tests were conducted successfully in a virtual machine environment.

Scripting languages like JavaScript are being integrated into commercial software to support easy file modification. For example, Adobe Acrobat accepts JavaScript to dynamically manipulate PDF files. To bridge the gap between the high-level scripts and the low-level languages (like C/C++) used to implement the software, a binding layer is necessary to transfer data and transform representations. However, due to the complexity of two sides, the binding code is prone to inconsistent semantics and security holes, which lead to severe vulnerabilities. Existing efforts for testing binding code merely focus on the script side, and thus miss bugs that require special program native inputs. In this paper, the researchers propose cooperative mutation, which modifies both the script code and the program native input to trigger bugs in binding code.

Cooper utilizes cooperative mutation to test the binding code of scripting languages to find memory-safe issues. Cooperative mutation simultaneously modifies the script code and the related document objects to explore various code paths of the binding code. To support cooperative mutation, the authors infer the relationship between script code and document objects to guide the two-dimensional mutation. They applied their tool Cooper on three popular commercial PDF tools, Adobe Acrobat, Foxit Reader, and Microsoft Word. Cooper detected 134 previously unknown bugs, which resulted in 33 CVE entries and 22K bug bounties.
