Descriptions

In radare2 through 4.0, there is an integer overflow for the variable new_token_size in the function r_asm_massemble at libr/asm/asm.c. This integer overflow will result in a Use-After-Free for the buffer tokens, which can be filled with arbitrary malicious data after the free. This allows remote attackers to cause a denial of service (application crash) or possibly execute arbitrary code via crafted input.

En radare2 versiones hasta la versión 4.0, hay un desbordamiento de enteros para la variable new_token_size en la función r_asm_massemble en el archivo libr/asm/asm.c. Este desbordamiento de enteros resultará en un Uso de la Memoria Previamente Liberada para los tokens del búfer, que se puede llenar con datos maliciosos arbitrarios después de la liberación. Esto permite a atacantes remotos causar una denegación de servicio (bloqueo de aplicación) o posiblemente ejecutar código arbitrario por medio de una entrada especialmente diseñada.
