Uncontrolled Recursion

Overview Affected versions of this package are vulnerable to Uncontrolled Recursion through the DAG-CBOR and DAG-JSON decoders. An attacker can cause a fatal stack overflow by submitting payloads with deeply nested collections. Remediation Upgrade github.com/ipld/go-ipld-prime/codec/dagcbor to...

go.opentelemetry.io/otel: go.opentelemetry.io/otel/schema/v1.0: go.opentelemetry.io/otel/schema/v1.1: OpenTelemetry-Go: Denial of Service due to file descriptor leak

A flaw was found in OpenTelemetry-Go before schema package version 0.0.17. ParseFile in go.opentelemetry.io/otel/schema/v1.0 and v1.1 opens a schema file and passes it to Parse without closing it, leaking one file descriptor per successful call. Repeated parsing in a long-running process can...
