{"id":"DEBIAN-CVE-2023-45667","details":"stb_image is a single file MIT licensed library for processing images.  If `stbi__load_gif_main` in `stbi_load_gif_from_memory` fails it returns a null pointer and may keep the `z` variable uninitialized. In case the caller also sets the flip vertically flag, it continues and calls `stbi__vertical_flip_slices` with the null pointer result value and the uninitialized `z` value. This may result in a program crash.","modified":"2026-09-15T09:02:22.860749412Z","published":"2023-10-21T00:15:09.143Z","upstream":["CVE-2023-45667"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2023-45667"}],"affected":[{"package":{"name":"libstb","ecosystem":"Debian:12","purl":"pkg:deb/debian/libstb?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.0~git20220908.8b5f1f3+ds-1","0.0~git20230129.5736b15+ds-1","0.0~git20230129.5736b15+ds-1.1","0.0~git20230129.5736b15+ds-1.1~exp1","0.0~git20230129.5736b15+ds-1.2","0.0~git20240715.f7f20f39fe4f+ds-1","0.0~git20241109.5c20573+ds-1","0.0~git20250907.fede005+ds-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2023-45667.json"}},{"package":{"name":"libstb","ecosystem":"Debian:13","purl":"pkg:deb/debian/libstb?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.0~git20241109.5c20573+ds-1","0.0~git20250907.fede005+ds-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2023-45667.json"}},{"package":{"name":"libstb","ecosystem":"Debian:14","purl":"pkg:deb/debian/libstb?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["0.0~git20241109.5c20573+ds-1","0.0~git20250907.fede005+ds-1"],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2023-45667.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
