CVE-2023-45676

Summary

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.
