Microsoft Security Advisory CVE-2025-55247 | .NET Denial of Service VulnerabilityExecutive summaryMicrosoft is releasing this security advisory to provide information about a vulnerability in .NET 8.0.xxx, .NET 9.0.xxx and .NET 10.0.xxx. This advisory also provides guidance on what developers can do to update their environments to remove this vulnerability. A vulnerability exists in .NET where predictable paths for MSBuild's temporary directories on Linux let another user create the directories ahead of MSBuild, leading to DoS of builds. This only affects .NET on Linux operating systems. AnnouncementAnnouncement for this issue can be found at https://github.com/dotnet/announcements/issues/370 Mitigation factorsProjects which do not utilize the DownloadFile build task are not susceptible to this vulnerability.

This advisory also provides guidance on what developers can do to update their environments to remove this vulnerability. A vulnerability exists in .NET where predictable paths for MSBuild's temporary directories on Linux let another user create the directories ahead of MSBuild, leading to DoS of builds. This only affects .NET on Linux operating systems. AnnouncementAnnouncement for this issue can be found at https://github.com/dotnet/announcements/issues/370 Mitigation factorsProjects which do not utilize the DownloadFile build task are not susceptible to this vulnerability.
