CVE-2023-45680

Summary

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.
