stb_vorbis is vulnerable to Out Of Bounds Write. The vulnerability is due to the manipulation of the len variable when processing ogg vorbis files with the f->vendor[len] = (char)'\0';' function. The attacker can exploit this issue by crafting a malicious file that causes the len read in start_decoder to be -1 and len + 1 become 0 when passed to setup_malloc leading to out of bounds write.
