{"id":"ALPINE-CVE-2023-45662","details":"stb_image is a single file MIT licensed library for processing images. When `stbi_set_flip_vertically_on_load` is set to `TRUE` and `req_comp` is set to a number that doesn’t match the real number of components per pixel, the library attempts to flip the image vertically. A crafted image file can trigger `memcpy` out-of-bounds read because `bytes_per_pixel` used to calculate `bytes_per_row` doesn’t match the real image array dimensions.","modified":"2026-11-03T06:32:02.944656399Z","published":"2023-10-21T00:15:08.867Z","upstream":["CVE-2023-45662"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2023-45662"}],"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-2023-45662.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-2023-45662.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-2023-45662.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-2023-45662.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-2023-45662.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-2023-45662.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:H"}]}
