Vulnerability from fkie_nvd - Published: 2023-11-24 19:15 - Updated: 2025-11-03 20:16
Severity ?
7.5 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N

Summary
OpenZFS through 2.1.13 and 2.2.x through 2.2.1, in certain scenarios involving applications that try to rely on efficient copying of file data, can replace file contents with zero-valued bytes and thus potentially disable security mechanisms. NOTE: this issue is not always security related, but can be security related in realistic situations. A possible example is cp, from a recent GNU Core Utilities (coreutils) version, when attempting to preserve a rule set for denying unauthorized access. (One might use cp when configuring access control, such as with the /etc/hosts.deny file specified in the IBM Support reference.) NOTE: this issue occurs less often in version 2.2.1, and in versions before 2.1.4, because of the default configuration in those versions.

(Se puede usar cp al configurar el control de acceso, como con el archivo /etc/hosts.deny especificado en la referencia de soporte de IBM). NOTA: este problema ocurre con menos frecuencia en la versi\u00f3n 2.2.1 y en versiones anteriores a la 2.1.4. debido a la configuraci\u00f3n predeterminada en esas versiones."
