      "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 in \u201cstsz\u201d decoder 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."

Una entrada MPEG-4 especialmente dise\u00f1ada en el decodificador \"stsz\" 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."
