{"id":"ALPINE-CVE-2023-45667","details":"stb_image is a single file MIT licensed library for processing images.\n\nIf `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":"2026-11-03T06:32:43.527222368Z","published":"2023-10-21T00:15:09.143Z","upstream":["CVE-2023-45667"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2023-45667"}],"affected":[{"package":{"name":"stb","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/stb?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0_git20231012-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-45667.json"}},{"package":{"name":"stb","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/stb?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0_git20231012-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-45667.json"}},{"package":{"name":"stb","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/stb?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0_git20231012-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-45667.json"}},{"package":{"name":"stb","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/stb?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0_git20231012-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-45667.json"}},{"package":{"name":"stb","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/stb?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0_git20231012-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-45667.json"}},{"package":{"name":"stb","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/stb?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"0_git20231012-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2023-45667.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
