{"id":"DEBIAN-CVE-2018-0739","details":"Constructed ASN.1 types with a recursive definition (such as can be found in PKCS7) could eventually exceed the stack given malicious input with excessive recursion. This could result in a Denial Of Service attack. There are no such structures used within SSL/TLS that come from untrusted sources so this is considered safe. Fixed in OpenSSL 1.1.0h (Affected 1.1.0-1.1.0g). Fixed in OpenSSL 1.0.2o (Affected 1.0.2b-1.0.2n).","modified":"2026-09-01T20:03:52.612767954Z","published":"2018-03-27T21:29:00.673Z","upstream":["CVE-2018-0739"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2018-0739"}],"affected":[{"package":{"name":"libtomcrypt","ecosystem":"Debian:12","purl":"pkg:deb/debian/libtomcrypt?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.18.2-1"}]}],"ecosystem_specific":{"urgency":"low"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2018-0739.json"}},{"package":{"name":"libtomcrypt","ecosystem":"Debian:13","purl":"pkg:deb/debian/libtomcrypt?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.18.2-1"}]}],"ecosystem_specific":{"urgency":"low"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2018-0739.json"}},{"package":{"name":"libtomcrypt","ecosystem":"Debian:14","purl":"pkg:deb/debian/libtomcrypt?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.18.2-1"}]}],"ecosystem_specific":{"urgency":"low"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2018-0739.json"}},{"package":{"name":"openssl","ecosystem":"Debian:12","purl":"pkg:deb/debian/openssl?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.1.0h-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2018-0739.json"}},{"package":{"name":"openssl","ecosystem":"Debian:13","purl":"pkg:deb/debian/openssl?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.1.0h-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2018-0739.json"}},{"package":{"name":"openssl","ecosystem":"Debian:14","purl":"pkg:deb/debian/openssl?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.1.0h-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2018-0739.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H"}]}
