Red Hat Product Security has assessed this issue as an Important severity vulnerability.\n\nA remote unauthenticated attacker may supply specially crafted Avro payloads containing excessively large block-count values followed by truncated or invalid data. Because the decoder continued iterating after the underlying reader entered an error state, affected applications may consume excessive CPU resources for extended periods of time, potentially leading to denial of service.\n\nThe currently available analysis demonstrates CPU exhaustion and service disruption but does not demonstrate confidentiality or integrity impact.
