This issue may allow context-dependent attackers to cause undefined behavior by exploiting improper pointer arithmetic.\n\nSince 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."},{"lang":"es","value":"Existe una vulnerabilidad en el componente inftrees.c de la librería zlib, que se incluye en PointCloudLibrary (PCL). Este problema podría permitir que atacantes dependientes del contexto provoquen un comportamiento indefinido al explotar una aritmética de punteros incorrecta.
