Microsoft PowerShell Core DoS And Security Feature Bypass Vulnerabilities (Linux)

This host is missing an important security update for PowerShell Core according to Microsoft security update January 2018.

Multiple flaws are due to, - An error in the open source versions of PowerShell Core when improper processing of XML documents by .NET Core occurs. - An error in the open source versions of PowerShell Core where an attacker could present a certificate that is marked invalid for a specific use, but a .NET Core component uses it for that purpose. This action disregards the Enhanced Key Usage tagging.

PowerShell Core version 6.0.0 before 6.0.1

Checks if a vulnerable version is present on the target host.

Update PowerShell Core to version 6.0.1 or later.
