CVE-2026-46384
iskorotkov/avro: Integer Overflow in Avro Decoder
Overview
Description
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 (GOARCH=386, arm, mips, wasm, etc.), the truncation paths can silently bypass byte-slice limits, select the wrong union branch, or hit the OCF negative-make panic via wrap. Three sub-issues are not 32-bit-specific: cumulative-size arithmetic overflow in arrayDecoder.Decode / mapDecoder.Decode / mapDecoderUnmarshaler.Decode (wraps at math.MaxInt64 on amd64 / arm64 and bypasses MaxSliceAllocSize / MaxMapAllocSize), math.MinInt negation in block-header handling, and make([]byte, size) with a negative size in OCF block reads — all three panic or bypass caps on any platform, giving an attacker a denial-of-service primitive there. This vulnerability is fixed in 2.33.0.

Solution
Update the Avro codec to version 2.33.0 or later to fix integer overflow and negative size issues.
- Update to Avro codec version 2.33.0 or later.
- Review and validate integer handling and bounds checks.

Action Type Old Value New Value Added Translation Title: avro de iskorotkov, Description: iskorotkov/avro es un códec Avro rápido para Go. Antes de la versión 2.33.0, varias rutas del decodificador Avro leían valores de 64 bits controlados por el atacante del formato de transmisión y los reducían a un entero (int) del tamaño de la plataforma antes de la verificación de límites, o los sumaban con aritmética de enteros con signo propensa a desbordamientos. En objetivos de 32 bits (GOARCH=386, arm, mips, wasm, etc.), las rutas de truncamiento pueden eludir silenciosamente los límites de las porciones de bytes, seleccionar la rama de unión incorrecta o provocar el pánico 'negative-make' de OCF a través de un 'wrap'. Tres subproblemas no son específicos de 32 bits: desbordamiento aritmético de tamaño acumulativo en arrayDecoder.Decode / mapDecoder.Decode / mapDecoderUnmarshaler.Decode (se ajusta en math.MaxInt64 en amd64 / arm64 y elude MaxSliceAllocSize / MaxMapAllocSize), negación de math.MinInt en el manejo de encabezados de bloque, y make([]byte, size) con un tamaño negativo en las lecturas de bloques OCF - los tres provocan pánico o eluden los límites en cualquier plataforma, dando al atacante una primitiva de denegación de servicio allí. Esta vulnerabilidad se corrige en la versión 2.33.0. -

Action Type Old Value New Value Added Description 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 (GOARCH=386, arm, mips, wasm, etc.), the truncation paths can silently bypass byte-slice limits, select the wrong union branch, or hit the OCF negative-make panic via wrap. Three sub-issues are not 32-bit-specific: cumulative-size arithmetic overflow in arrayDecoder.Decode / mapDecoder.Decode / mapDecoderUnmarshaler.Decode (wraps at math.MaxInt64 on amd64 / arm64 and bypasses MaxSliceAllocSize / MaxMapAllocSize), math.MinInt negation in block-header handling, and make([]byte, size) with a negative size in OCF block reads — all three panic or bypass caps on any platform, giving an attacker a denial-of-service primitive there. This vulnerability is fixed in 2.33.0. Added CVSS V4.0 AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/MVI:X/MVA:X/MSC:X/MSI:X/MSA:X/S:X/AU:X/R:X/V:X/RE:X/U:X Added CWE CWE-190 Added Reference https://github.com/iskorotkov/avro/security/advisories/GHSA-mc57-h6j3-3hmv
