Descriptions
.NET and Visual Studio Remote Code Execution Vulnerability
A flaw was found in dotnet. When closing an HTTP/3 stream while application code is writing to the response body, a race condition can cause a use-after-free.
Brennan Conroy discovered that the .NET Kestrel web server did not properly handle closing HTTP/3 streams under certain circumstances. An attacker could possibly use this issue to achieve remote code execution. This vulnerability only impacted Ubuntu 22.04 LTS and Ubuntu 24.04 LTS. It was discovered that .NET components designed to process malicious input were susceptible to hash flooding attacks. An attacker could possibly use this issue to cause a denial of service, resulting in a crash.
