Synopsis

The remote Red Hat host is missing one or more security updates for .NET Core.

Description

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2017:3248 advisory.

New versions of .NET Core that address several security vulnerabilities are now available. The updated versions are .NET Core 1.0.8, 1.1.5 and 2.0.3.

Security Fix(es):

* By providing an invalid culture, an attacker can cause a recursive lookup that leads to a denial of service when running on certain Windows platforms. (CVE-2017-8585)

* Supplying a specially crafted certificate can cause an infinite X509Chain, resulting in a denial of service. (CVE-2017-11770)

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL .NET Core package based on the guidance in RHSA-2017:3248.
