CVE-2023-45681

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.
