Descriptions

stb_vorbis is a single file MIT licensed library for processing ogg vorbis files. A crafted file may trigger memory allocation failure in `start_decoder`. In that case the function returns early, the `f->comment_list` is set to `NULL`, but `f->comment_list_length` is not reset. Later in `vorbis_deinit` it tries to dereference the `NULL` pointer. This issue may lead to denial of service.

stb_vorbis es una librería de archivo único con licencia MIT para procesar archivos ogg vorbis. Un archivo manipulado puede provocar una falla en la asignación de memoria en `start_decoder`. En ese caso, la función regresa antes, `f->comment_list` se establece en `NULL`, pero `f->comment_list_length` no se restablece. Más adelante en `vorbis_deinit` intenta eliminar la referencia al puntero `NULL`. Este problema puede provocar la denegación del servicio.
