{"id":"ALPINE-CVE-2019-3823","details":"libcurl versions from 7.34.0 to before 7.64.0 are vulnerable to a heap out-of-bounds read in the code handling the end-of-response for SMTP. If the buffer passed to `smtp_endofresp()` isn't NUL terminated and contains no character ending the parsed number, and `len` is set to 5, then the `strtol()` call reads beyond the allocated buffer. The read contents will not be returned to the caller.","modified":"2026-09-10T06:17:54.541568847Z","published":"2019-02-06T20:29:00.400Z","upstream":["CVE-2019-3823"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2019-3823"}],"affected":[{"package":{"name":"curl","ecosystem":"Alpine:v3.10","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.64.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-3823.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.11","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.64.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-3823.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.12","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.64.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-3823.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.13","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.64.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-3823.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.14","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.64.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-3823.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.15","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.64.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-3823.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.16","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.64.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-3823.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.17","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.64.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-3823.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.18","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.64.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-3823.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.19","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.64.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-3823.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.20","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.64.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-3823.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.21","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.64.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-3823.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.22","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.64.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-3823.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.23","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.64.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/ALPINE-CVE-2019-3823.json"}},{"package":{"name":"curl","ecosystem":"Alpine:v3.24","purl":"pkg:apk/alpine/curl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"7.64.0-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/alpine/A
