stb_vorbis is a single file MIT licensed library for processing ogg vorbis
files. A crafted file may trigger out of bounds write in f->vendor[i] = get8_packet(f);. The root cause is an integer overflow in setup_malloc.
A sufficiently large value in the variable sz overflows with sz+7 in
and the negative value passes the maximum available memory buffer check.
This issue may lead to code execution.
