CVE-2023-45676

Summary

CVE-2023-45676 is a vulnerability affecting the stb_vorbis library, which is used for processing Ogg Vorbis files. A specially crafted file can trigger an out-of-bounds write in the function `setup_malloc`. This issue arises due to an integer overflow in the variable `sz`, which overflows by 7 bytes and results in a negative value. Despite passing the maximum available memory buffer check, this negative value leads to memory corruption and potentially code execution. The MIT-licensed library is at risk due to this vulnerability.
