CVE-2025-55653

GPAC MP4Box v2.4 was discovered to contain a floating point exception in the gf_parse_lfrac function (utils/error.c). Processing a crafted MP4 file containing a zero-denominator fraction string causes gf_parse_lfrac() to divide by zero, terminating the process with SIGFPE.

Summary		(es) Se descubrió que GPAC MP4Box v2.4 contenía una excepción de punto flotante en la función gf_parse_lfrac (utils/error.c). El procesamiento de un archivo MP4 manipulado que contiene una cadena de fracción con denominador cero provoca que gf_parse_lfrac() divida por cero, terminando el proceso con SIGFPE.
