      "value": "RISC Zero is a zero-knowledge verifiable general computing platform based on zk-STARKs and the RISC-V microarchitecture. In versions 2.0.2 and below of risc0-zkvm-platform, when the zkVM guest calls sys_read, the host is able to use a crafted response to write to an arbitrary memory location in the guest. This capability can be leveraged to execute arbitrary code within the guest. As sys_read is the mechanism by which input is requested by the guest, all guest programs built with the affected versions are vulnerable. This critically compromises the soundness guarantees of the guest program. Other affected packages include risc0-aggregation versions below 0.9,  risc0-zkos-v1compat below 2.1.0, risc0-zkvm versions between 3.0.0-rc.1 and 3.0.1. This issue has been fixed in the following versions: risc0-zkvm-platform 2.1.0, risc0-zkos-v1compat 2.1.0, risc0-aggregation 0.9, and risc0-zkvm 2.3.2 and 3.0.3."

      "value": "RISC Zero es una plataforma de computación general verificable de conocimiento cero basada en zk-STARKs y la microarquitectura RISC-V. En las versiones 2.0.2 e inferiores de risc0-zkvm-platform, cuando el invitado zkVM llama a sys_read, el anfitrión puede usar una respuesta manipulada para escribir en una ubicación de memoria arbitraria en el invitado. Esta capacidad puede ser aprovechada para ejecutar código arbitrario dentro del invitado. Dado que sys_read es el mecanismo por el cual el invitado solicita la entrada, todos los programas de invitado construidos con las versiones afectadas son vulnerables. Esto compromete críticamente las garantías de solidez del programa de invitado. Otros paquetes afectados incluyen risc0-aggregation versiones inferiores a 0.9, risc0-zkos-v1compat inferiores a 2.1.0, risc0-zkvm versiones entre 3.0.0-rc.1 y 3.0.1. Este problema ha sido solucionado en las siguientes versiones: risc0-zkvm-platform 2.1.0, risc0-zkos-v1compat 2.1.0, risc0-aggregation 0.9, y risc0-zkvm 2.3.2 y 3.0.3."
