Descriptions

stb_vorbis is a single file MIT licensed library for processing ogg vorbis files. A crafted file may trigger memory write past an allocated heap buffer in `start_decoder`. The root cause is a potential integer overflow in `sizeof(char*) * (f->comment_list_length)` which may make `setup_malloc` allocate less memory than required. Since there is another integer overflow an attacker may overflow it too to force `setup_malloc` to return 0 and make the exploit more reliable. This issue may lead to code execution.

stb_vorbis es una librería de archivo único con licencia MIT para procesar archivos ogg vorbis. Un archivo manipulado puede activar la escritura en memoria más allá de un búfer de montón asignado en `start_decoder`. La causa principal es un posible desbordamiento de enteros en `sizeof(char*) * (f->comment_list_length)` que puede hacer que `setup_malloc` asigne menos memoria de la requerida. Dado que hay otro desbordamiento de enteros, un atacante también puede desbordarlo para forzar a `setup_malloc` a devolver 0 y hacer que el exploit sea más confiable. Este problema puede provocar la ejecución del código.
