Red Hat Security Advisory: Migration Toolkit for Containers (MTC) 1.5.1 security and bug fix update
Notes
Topic
An update is now available for the Migration Toolkit for Containers (MTC) 1.5.1.
Red Hat Product Security has rated this update as having a security impact of Moderate. 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
The Migration Toolkit for Containers (MTC) enables you to migrate
Kubernetes resources, persistent volume data, and internal container images
between OpenShift Container Platform clusters, using the MTC web console or the Kubernetes API.
Security fixes:
* golang: net: lookup functions may return invalid host names (CVE-2021-33195)
* golang: archive/zip: malformed archive may cause panic or memory exhaustion (CVE-2021-33196)
* golang: net/http/httputil: ReverseProxy forwards connection headers if first one is empty (CVE-2021-33197)
* golang: math/big.Rat: may cause a panic or an unrecoverable fatal error if passed inputs with very large exponents (CVE-2021-33198)
* golang: crypto/tls: certificate of wrong type is causing TLS client to panic (CVE-2021-34558)
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.

Additionally only core OpenShift distributed tracing components have been listed.\n\n* Although Serverless does ship the affected package, it does not make use of the actual package and hence the impact is low.\n\n* Because Service Telemetry Framework1.2 will be retiring soon and the flaw\u0027s impact is lower, no update will be provided at this time for STF1.2\u0027s smart-gateway-container and sg-core-container.",

A panic can be triggered by an attacker in a privileged network position without access to the server certificate\u0027s private key, as long as a trusted ECDSA or Ed25519 certificate for the server exists (or can be issued), or the client is configured with Config.InsecureSkipVerify.

It is possible for components that make client connections to malicious servers to be exploited, however the maximum impact is a crash.
