Infinite loop

Overview Affected versions of this package are vulnerable to Infinite loop through the Avro Decoder process. An attacker can exhaust CPU resources by providing a specially crafted payload with a large block-count value, causing the decoder to perform excessive iterations before propagating an...

CVE-2026-46384

iskorotkov/avro is a fast Go Avro codec. Prior to 2.33.0, several Avro decoder paths read attacker-controlled 64-bit values from the wire format and either narrowed them to platform-sized int before bounds-checking, or summed them with overflow-prone signed-int arithmetic. On 32-bit targets...

CVE-2026-46385 iskorotkov/avro: CPU Exhaustion in Avro Decoder

iskorotkov/avro is a fast Go Avro codec. Prior to 2.33.0, the Avro array and map decoders looped over an attacker-controlled block-count value without checking the underlying reader's error state inside the loop body. Reader.ReadBlockHeader returns the count as a Go int, which is 64-bit on amd64 ...

CVE-2026-46384

CVE-2026-46384 affects iskorotkov/avro (Go) prior to v2.33.0. The root causes are integer overflow and narrowing in Avro decoding paths, including: ReadBlockHeader narrowing on 32-bit targets; cumulative size overflow in arrayDecoder.Decode / mapDecoder.Decode / mapDecoderUnmarshaler.Decode; MinI...

iskorotkov/avro: CPU Exhaustion in Decoder

CPU Exhaustion in Avro Decoder via Unbounded Block-Count Iteration Summary The Avro array and map decoders looped over an attacker-controlled block-count value without checking the underlying reader's error state inside the loop body. Reader.ReadBlockHeader returns the count as a Go int, which is...
