FKIE_CVE-2025-6297

Vulnerability from fkie_nvd - Published: 2025-07-01 17:15 - Updated: 2025-08-19 17:50
Severity ?
8.2 (High) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:L/A:N
Summary
It was discovered that dpkg-deb does not properly sanitize directory permissions when extracting a control member into a temporary directory, which is documented as being a safe operation even on untrusted data. This may result in leaving temporary files behind on cleanup. Given automated and repeated execution of dpkg-deb commands on adversarial .deb packages or with well compressible files, placed inside a directory with permissions not allowing removal by a non-root user, this can end up in a DoS scenario due to causing disk quota exhaustion or disk full conditions.

Esto puede resultar en la p\u00e9rdida de archivos temporales durante la depuraci\u00f3n. Si se ejecutan comandos dpkg-deb de forma automatizada y repetida en paquetes .deb adversarios o con archivos bien comprimibles, ubicados dentro de un directorio con permisos que impiden la eliminaci\u00f3n por parte de un usuario no root, esto puede provocar un ataque de denegaci\u00f3n de servicio (DoS) al causar el agotamiento de la cuota de disco o la saturaci\u00f3n del disco."
