{"id":"ALPINE-CVE-2018-0732","details":"During key agreement in a TLS handshake using a DH(E) based ciphersuite a malicious server can send a very large prime value to the client. This will cause the client to spend an unreasonably long period of time generating a key for this prime resulting in a hang until the client has finished. This could be exploited in a Denial Of Service attack. Fixed in OpenSSL 1.1.0i-dev (Affected 1.1.0-1.1.0h). Fixed in OpenSSL 1.0.2p-dev (Affected 1.0.2-1.0.2o).","modified":"2026-07-06T00:30:21.479701923Z","published":"2018-06-12T13:29:00.207Z","upstream":["CVE-2018-0732"],"references":[{"type":"ADVISORY","url":"https://security.alpinelinux.org/vuln/CVE-2018-0732"}],"affected":[{"package":{"name":"libressl","ecosystem":"Alpine:v3.10","purl":"pkg:apk/alpine/libressl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.7.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2018-0732.json"}},{"package":{"name":"libressl","ecosystem":"Alpine:v3.11","purl":"pkg:apk/alpine/libressl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.7.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2018-0732.json"}},{"package":{"name":"libressl","ecosystem":"Alpine:v3.12","purl":"pkg:apk/alpine/libressl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.7.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2018-0732.json"}},{"package":{"name":"libressl","ecosystem":"Alpine:v3.13","purl":"pkg:apk/alpine/libressl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.7.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2018-0732.json"}},{"package":{"name":"libressl","ecosystem":"Alpine:v3.7","purl":"pkg:apk/alpine/libressl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.6.5-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2018-0732.json"}},{"package":{"name":"libressl","ecosystem":"Alpine:v3.8","purl":"pkg:apk/alpine/libressl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.7.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2018-0732.json"}},{"package":{"name":"libressl","ecosystem":"Alpine:v3.9","purl":"pkg:apk/alpine/libressl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.7.4-r0"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2018-0732.json"}},{"package":{"name":"openssl","ecosystem":"Alpine:v3.3","purl":"pkg:apk/alpine/openssl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.0.2"},{"fixed":"1.0.2o-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2018-0732.json"}},{"package":{"name":"openssl","ecosystem":"Alpine:v3.4","purl":"pkg:apk/alpine/openssl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.0.2"},{"fixed":"1.0.2o-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2018-0732.json"}},{"package":{"name":"openssl","ecosystem":"Alpine:v3.5","purl":"pkg:apk/alpine/openssl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.0.2"},{"fixed":"1.0.2o-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2018-0732.json"}},{"package":{"name":"openssl","ecosystem":"Alpine:v3.6","purl":"pkg:apk/alpine/openssl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.0.2"},{"fixed":"1.0.2o-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2018-0732.json"}},{"package":{"name":"openssl","ecosystem":"Alpine:v3.7","purl":"pkg:apk/alpine/openssl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.0.2"},{"fixed":"1.0.2o-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2018-0732.json"}},{"package":{"name":"openssl","ecosystem":"Alpine:v3.8","purl":"pkg:apk/alpine/openssl?arch=source"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"1.0.2"},{"fixed":"1.0.2o-r1"}]}],"ecosystem_specific":{},"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/alpine/ALPINE-CVE-2018-0732.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
