{"id":"ALPINE-CVE-2023-45663","details":"stb_image is a single file MIT licensed library for processing images. The stbi__getn function reads a specified number of bytes from context (typically a file) into the specified buffer. In case the file stream points to the end, it returns zero. There are two places where its return value is not checked: In the `stbi__hdr_load` function and in the `stbi__tga_load` function. The latter of the two is likely more exploitable as an attacker may also control the size of an uninitialized buffer.","modified":"2026-11-03T06:32:43.609638380Z","published":"2023-10-21T00:15:08.930Z","upstream":["CVE-2023-45663"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2023-45663"}],"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-2023-45663.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-2023-45663.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-2023-45663.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-2023-45663.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-2023-45663.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-2023-45663.json"}}],"schema_version":"1.9.2","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:N/A:N"}]}
