Descriptions

stb_vorbis is a single file MIT licensed library for processing ogg vorbis files. A crafted file may trigger out of bounds read in `DECODE` macro when `var` is negative. As it can be seen in the definition of `DECODE_RAW` a negative `var` is a valid value. This issue may be used to leak internal memory allocation information.

stb_vorbis es una librería de archivo único con licencia MIT para procesar archivos ogg vorbis. Un archivo manipulado puede desencadenar una lectura fuera de límites en la macro `DECODE` cuando `var` es negativo. Como se puede ver en la definición de `DECODE_RAW`, una `var` negativa es un valor válido. Este problema puede utilizarse para filtrar información de asignación de memoria interna.
