FKIE_CVE-2021-39228

Vulnerability from fkie_nvd - Published: 2021-09-17 14:15 - Updated: 2024-11-21 06:18
Severity ?
6.5 (Medium) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:N
9.8 (Critical) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Summary
Tremor is an event processing system for unstructured data. A vulnerability exists between versions 0.7.2 and 0.11.6. This vulnerability is a memory safety Issue when using `patch` or `merge` on `state` and assign the result back to `state`. In this case, affected versions of Tremor and the tremor-script crate maintains references to memory that might have been freed already. And these memory regions can be accessed by retrieving the `state`, e.g. send it over TCP or HTTP. This requires the Tremor server (or any other program using tremor-script) to execute a tremor-script script that uses the mentioned language construct. The issue has been patched in version 0.11.6 by removing the optimization and always cloning the target expression of a Merge or Patch. If an upgrade is not possible, a possible workaround is to avoid the optimization by introducing a temporary variable and not immediately reassigning to `state`.

      "value": "Tremor es un sistema de procesamiento de eventos para datos no estructurados. Se presenta una vulnerabilidad entre las versiones 0.7.2 y 0.11.6. Esta vulnerabilidad es un problema de seguridad de memoria cuando es usado \"patch\" o \"merge\" en \"state\" y se asigna el resultado de nuevo a \"state\". En este caso, las versiones afectadas de Tremor y el crate tremor-script mantienen referencias a la memoria que podr\u00edan haber sido liberadas ya. Y estas regiones de memoria pueden ser accedidas al recuperar el \"state\", por ejemplo, envi\u00e1ndolo por TCP o HTTP. Esto requiere que el servidor Tremor (o cualquier otro programa usando tremor-script) ejecute un script tremor-script que use la construcci\u00f3n de lenguaje mencionada. El problema ha sido parcheado en la versi\u00f3n 0.11.6, al eliminar la optimizaci\u00f3n y clonando siempre la expresi\u00f3n de destino de una Fusi\u00f3n o Parche. Si no es posible una actualizaci\u00f3n, una posible soluci\u00f3n es evitar la optimizaci\u00f3n introduciendo una variable temporal y no reasignando inmediatamente a \"state\""

Summary
Tremor is an event processing system for unstructured data. A vulnerability exists between versions 0.7.2 and 0.11.6. This vulnerability is a memory safety Issue when using `patch` or `merge` on `state` and assign the result back to `state`. In this case, affected versions of Tremor and the tremor-script crate maintains references to memory that might have been freed already. And these memory regions can be accessed by retrieving the `state`, e.g. send it over TCP or HTTP. This requires the Tremor server (or any other program using tremor-script) to execute a tremor-script script that uses the mentioned language construct. The issue has been patched in version 0.11.6 by removing the optimization and always cloning the target expression of a Merge or Patch. If an upgrade is not possible, a possible workaround is to avoid the optimization by introducing a temporary variable and not immediately reassigning to `state`.

Summary
Tremor is an event processing system for unstructured data. A vulnerability exists between versions 0.7.2 and 0.11.6. This vulnerability is a memory safety Issue when using `patch` or `merge` on `state` and assign the result back to `state`. In this case, affected versions of Tremor and the tremor-script crate maintains references to memory that might have been freed already. And these memory regions can be accessed by retrieving the `state`, e.g. send it over TCP or HTTP. This requires the Tremor server (or any other program using tremor-script) to execute a tremor-script script that uses the mentioned language construct. The issue has been patched in version 0.11.6 by removing the optimization and always cloning the target expression of a Merge or Patch. If an upgrade is not possible, a possible workaround is to avoid the optimization by introducing a temporary variable and not immediately reassigning to `state`.
