Red Hat Security Advisory: Red Hat OpenShift Service Mesh 1.0.3 RPMs security update

Notes

Topic
Red Hat OpenShift Service Mesh 1.0.3. Red Hat Product Security has rated this update as having a security impact of Critical. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.
Details
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.
