"value": "Multiple exploitable integer overflow vulnerabilities exist within the MPEG-4 decoding functionality of the GPAC Project on Advanced Content library v1.0.1. A specially crafted MPEG-4 input can cause an integer overflow due to unchecked arithmetic resulting in a heap-based buffer overflow that causes memory corruption. An attacker can convince a user to open a video to trigger this vulnerability."

"value": "Se presentan m\u00faltiples vulnerabilidades de desbordamiento de enteros explotables dentro de la funcionalidad MPEG-4 decoding de GPAC Project on Advanced Content library versi\u00f3n v1.0.1. Una entrada MPEG-4 especialmente dise\u00f1ada puede causar un desbordamiento de enteros debido a una aritm\u00e9tica no comprobada, resultando en un desbordamiento del b\u00fafer en la regi\u00f3n heap de la memoria que causa una corrupci\u00f3n de memoria. Un atacante puede convencer a un usuario de que abra un v\u00eddeo para desencadenar esta vulnerabilidad."
