      "value": "An issue was discovered in stb stb_image.h 2.27. The PNM loader incorrectly interpreted 16-bit PGM files as 8-bit when converting to RGBA, leading to a buffer overflow when later reinterpreting the result as a 16-bit buffer. An attacker could potentially have crashed a service using stb_image, or read up to 1024 bytes of non-consecutive heap data without control over the read location."

El cargador de PNM interpretaba incorrectamente los archivos PGM de 16 bits como de 8 bits cuando los convert\u00eda a RGBA, conllevando a un desbordamiento del b\u00fafer cuando se reinterpreta posteriormente el resultado como un b\u00fafer de 16 bits. Un atacante podr\u00eda potencialmente bloquear un servicio usando stb_image, o leer hasta 1024 bytes de datos de la pila no consecutivos sin control sobre la ubicaci\u00f3n de lectura"
