    Title
    Datadog PHP Tracer: Improper parsing of W3C baggage headers may lead to DoS
    Summary
    The Datadog PHP Tracer provides application performance monitoring and distributed tracing for PHP. Prior to 1.19.2, ddtrace_deserialize_baggage in ext/distributed_tracing_headers.c parses incoming W3C baggage HTTP headers without enforcing DD_TRACE_BAGGAGE_MAX_ITEMS or DD_TRACE_BAGGAGE_MAX_BYTES. A remote unauthenticated client can send an arbitrarily large number of comma-separated key-value pairs or a single oversized value, causing the tracer to allocate hash-map entries and consume unbounded CPU and memory on each request. Baggage extraction is enabled by default in most affected deployments unless baggage is removed from DD_TRACE_PROPAGATION_STYLE or DD_TRACE_PROPAGATION_STYLE_EXTRACT. This issue is fixed in version 1.19.2.
