{"id":"CVE-2023-45679","summary":"Attempt to free an uninitialized memory pointer in vorbis_deinit in stb_vorbis","details":"stb_vorbis is a single file MIT licensed library for processing ogg vorbis files. A crafted file may trigger memory allocation failure in `start_decoder`. In that case the function returns early, but some of the pointers in `f-\u003ecomment_list` are left initialized and later `setup_free` is called on these pointers in `vorbis_deinit`. This issue may lead to code execution.","modified":"2026-03-13T07:45:12.093882Z","published":"2023-10-20T23:26:52.650Z","related":["openSUSE-SU-2025:0037-1"],"database_specific":{"cwe_ids":["CWE-415"],"cna_assigner":"GitHub_M","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/45xxx/CVE-2023-45679.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/45xxx/CVE-2023-45679.json"},{"type":"WEB","url":"https://github.com/nothings/stb/blob/5736b15f7ea0ffb08dd38af21067c314d6a3aae9/stb_vorbis.c#L3660-L3677"},{"type":"WEB","url":"https://github.com/nothings/stb/blob/5736b15f7ea0ffb08dd38af21067c314d6a3aae9/stb_vorbis.c#L4208-L4215"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-45679"},{"type":"ADVISORY","url":"https://securitylab.github.com/advisories/GHSL-2023-145_GHSL-2023-151_stb_image_h/"}],"affected":[{"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2023-45679.json","unresolved_ranges":[{"events":[{"introduced":"0"},{"last_affected":"1.22"}]}]}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L"}]}
