FKIE_CVE-2025-4638

Vulnerability from fkie_nvd - Published: 2025-05-14 18:15 - Updated: 2025-10-21 14:10
Severity ?
9.8 (Critical) - CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H
Summary
A vulnerability exists in the inftrees.c component of the zlib library, which is bundled within the PointCloudLibrary (PCL). This issue may allow context-dependent attackers to cause undefined behavior by exploiting improper pointer arithmetic. Since version 1.14.0, PCL by default uses a zlib installation from the system, unless the user sets WITH_SYSTEM_ZLIB=FALSE. So this potential vulnerability is only relevant if the PCL version is older than 1.14.0 or the user specifically requests to not use the system zlib.

Este problema podr\u00eda permitir que atacantes dependientes del contexto provoquen un comportamiento indefinido al explotar una aritm\u00e9tica de punteros incorrecta. Desde la versi\u00f3n 1.14.0, PCL utiliza de forma predeterminada una instalaci\u00f3n de zlib desde el sistema, a menos que el usuario configure WITH_SYSTEM_ZLIB=FALSE. Por lo tanto, esta posible vulnerabilidad solo es relevante si la versi\u00f3n de PCL es anterior a la 1.14.0 o si el usuario solicita espec\u00edficamente no usar la zlib del sistema."
