TITLE

.NET Core and PowerShell Core Service disruption in (DoS) Vulnerabilities

Trust: 0.8

sources: JVNDB: JVNDB-2018-002560

DESCRIPTION

.NET Core 1.0, .NET Core 1.1, NET Core 2.0 and PowerShell Core 6.0.0 allow a denial of Service vulnerability due to how specially crafted requests are handled, aka ".NET Core Denial of Service Vulnerability". Microsoft .NET is prone to a denial-of-service vulnerability. Successful exploits will attackers to cause performance to degrade resulting in a denial of service condition. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Low: .NET Core on Red Hat Enterprise Linux security update Advisory ID: RHSA-2018:0522-01 Product: .NET Core on Red Hat Enterprise Linux Advisory URL: https://access.redhat.com/errata/RHSA-2018:0522 Issue date: 2018-03-14 CVE Names: CVE-2018-0875 ===================================================================== 1.
