usn-7210-1
Vulnerability from osv_ubuntu
It was discovered that .NET did not properly handle input provided to its Convert.TryToHexString method. An attacker could possibly use this issue to execute arbitrary code. (CVE-2025-21171)
It was discovered that .NET did not properly handle an integer overflow when processing certain specially crafted files. An attacker could possibly use this issue to execute arbitrary code. (CVE-2025-21172)
Daniel Plaisted and Noah Gilson discovered that .NET insecurely handled temporary file usage which could result in malicious package dependency injection. An attacker could possibly use this issue to elevate privileges. (CVE-2025-21173)
It was discovered that .NET did not properly perform input data validation when processing certain specially crafted files. An attacker could possibly use this issue to execute arbitrary code. (CVE-2025-21176)
