RHEL 7 / 8 : Red Hat OpenShift Service Mesh 1.0.3 RPMs (RHSA-2019:4222)

critical Nessus Plugin ID 132031

Synopsis

The remote Red Hat host is missing one or more security updates for Red Hat OpenShift Service Mesh 1.0.3 RPMs.

Description

The remote Redhat Enterprise Linux 7 / 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2019:4222 advisory.

Red Hat OpenShift Service Mesh is Red Hat's distribution of the Istio service mesh project, tailored for installation into an on-premise OpenShift Container Platform installation.

This advisory covers the RPM packages for the OpenShift Service Mesh 1.0.3 release.

Security Fix(es):

* An untrusted remote client may send HTTP/2 requests that write to the heap outside of the request buffers when the upstream is HTTP/1 (CVE-2019-18801)

* Malformed request header may cause bypass of route matchers resulting in escalation of privileges or information disclosure (CVE-2019-18802)

* Malformed HTTP request without the Host header may cause abnormal termination of the Envoy process (CVE-2019-18838)

For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and other related information, refer to the CVE page(s) listed in the References section.

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 Red Hat OpenShift Service Mesh 1.0.3 RPMs package based on the guidance in RHSA-2019:4222.
