FKIE_CVE-2020-11105

Vulnerability from fkie_nvd - Published: 2020-03-30 22:15 - Updated: 2024-11-21 04:56
Severity ?
9.8 (Critical) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Summary
An issue was discovered in USC iLab cereal through 1.3.0. It employs caching of std::shared_ptr values, using the raw pointer address as a unique identifier. This becomes problematic if an std::shared_ptr variable goes out of scope and is freed, and a new std::shared_ptr is allocated at the same address. Serialization fidelity thereby becomes dependent upon memory layout. In short, serialized std::shared_ptr variables cannot always be expected to serialize back into their original values. This can have any number of consequences, depending on the context within which this manifests.

      "value": "Se detect\u00f3 un problema en USC iLab cereal versiones hasta 1.3.0. Emplea el almacenamiento cach\u00e9 de los valores de std::shared_ptr, utilizando la direcci\u00f3n de puntero sin procesar como un identificador \u00fanico. Esto se vuelve problem\u00e1tico si una variable std::shared_ptr sale del alcance y es liberada, y una nueva std::shared_ptr es asignada en la misma direcci\u00f3n. La fidelidad de serializaci\u00f3n se vuelve dependiente del dise\u00f1o de la memoria. En resumen, no siempre puede esperarse que las variables std::shared_ptr serializadas sean serializadas de vuelta a sus valores originales. Esto puede tener muchas consecuencias, dependiendo del contexto dentro del cual se manifieste."
