Description Trevor Jay 2017-11-14 14:46:20 UTC
By providing an invalid culture, an attacker can cause a recursive lookup that leads to a denial of service.

Comment 3 Omair Majid 2017-11-15 20:32:39 UTC
The upstream note about this CVE (https://github.com/dotnet/announcements/issues/34) states:

System administrators are advised to update their .NET Core runtimes to versions 1.0.7 and 1.1.4.

It looks like this was fixed even before .NET Core 1.1.5 and 1.0.8.

The announcement also states:

.NET Core 1.x applications are only affected if running on Windows 10 or Windows 2016.

This doesnt appear to affect Linux. But due to how self-contained applications can be built for other platforms, this needs to be fixed everywhere.
