Red Hat Security Advisory: RHTAS 1.3.8 - Red Hat Trusted Artifact Signer Release
Severity
Important
Notes
Topic: The 1.3.8 release of Red Hat Trusted Artifact Signer OpenShift Operator.
For more details please visit the product documentation at https://access.redhat.com/documentation/en-us/red_hat_trusted_artifact_signer/1.3
Details: The RHTAS Operator can be used with OpenShift Container Platform 4.16, 4.17, 4.18, 4.19, 4.20 and 4.21

A flaw was found in OpenTelemetry-Go. This vulnerability allows a remote attacker to cause a Denial of Service (DoS) by sending oversized or invalid baggage headers. The `Parse` function, in affected versions, failed to reject raw-length inputs, leading to excessive processing and error logging when handling these large inputs.

Threats
Impact
Important
A flaw was found in etcd, a distributed key-value store. A remote attacker can exploit this by opening numerous TCP connections to an etcd TLS listener without completing the TLS handshake. This action causes the `tlsListener.acceptLoop` to spawn an unbounded number of goroutines, which consume excessive memory. This resource exhaustion leads to a Denial of Service (DoS) for the etcd cluster and, consequently, for the Kubernetes control plane it supports.
