EUVD-2026-33444

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-2026-46385 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.

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...

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...

Avro 资源管理错误漏洞

Avro is a fast Go Avro decoder developed by hamba. Versions prior to 2.33.0 contained a resource management vulnerability. This vulnerability stemmed from the Avro array and mapping decoders’ tendency to loop through a counter controlled by the attacker without checking the error status of the...

Avro 输入验证错误漏洞

Avro is a fast Go Avro decoder developed by hamba. Versions prior to Avro 2.33.0 contained a vulnerability related to input validation errors. This vulnerability stemmed from multiple Avro decoder paths reading 64-bit values controlled by an attacker and truncating or using overflow signed intege...

Integer Overflow

github.com/iskorotkov/avro is vulnerable to integer overflow. The vulnerability is due to improper handling of attacker-controlled 64-bit values, integer truncation, and overflow-prone arithmetic in multiple decoder paths, which allows an attacker to exploit untrusted Avro streams to trigger...
