Description OSIDB Bzimport 2025-10-10 13:35:21 UTC 
A vulnerability exists in .NET Core where predictable paths for
MSBuild's temporary directories on Linux let another user create the
directories ahead of MSBuild, leading to DoS of builds.

Affected versions:
.NET 8.0 (that's the RHEL dotnet8.0 package)
.NET 9.0 (that's the RHEL dotnet9.0 package)
.NET 10.0 (that's the RHEL dotnet10.0 package)
