An off-by-one error when processing malformed TLS-CBC ciphertext could cause the receiving side to include in the HMAC computation exactly 64K bytes of data following the record buffer, aka an over-read. The MAC comparison will subsequently fail and the connection will be closed. This could be used for denial of service. No information leak occurs.","references":[{"reference_url":"https://api.first.org/data/v1/epss?cve=CVE-2018-9860","reference_id":"","reference_type":"","scores":[{"value":"0.00499","scoring_system":"epss","scoring_elements":"0.65823","published_at":"2026-04-01T12:55:00Z"},{"value":"0.00499","scoring_system":"epss","scoring_elements":"0.65871","published_at":"2026-04-02T12:55:00Z"},{"value":"0.00499","scoring_system":"epss","scoring_elements":"0.65901","published_at":"2026-04-04T12:55:00Z"},{"value":"0.00499","scoring_system":"epss","scoring_elements":"0.65866","published_at":"2026-04-07T12:55:00Z"},{"value":"0.00499","scoring_system":"epss","scoring_elements":"0.65918","published_at":"2026-04-08T12:55:00Z"},{"value":"0.00499","scoring_system":"epss","scoring_elements":"0.65929","published_at":"2026-04-09T12:55:00Z"},{"value":"0.00499","scoring_system":"epss","scoring_elements":"0.65947","published_at":"2026-04-11T12:55:00Z"},{"value":"0.00499","scoring_system":"epss","scoring_elements":"0.65934","published_at":"2026-04-12T12:55:00Z"},{"value":"0.00499","scoring_system":"epss","scoring_elements":"0.65904","published_at":"2026-04-13T12:55:00Z"},{"value":"0.00499","scoring_system":"epss","scoring_elements":"0.65939","published_at":"2026-04-16T12:55:00Z"},{"value":"0.00499","scoring_system":"epss","scoring_elements":"0.65954","published_at":"2026-04-18T12:55:00Z"},{"value":"0.00499","scoring_system":"epss","scoring_elements":"0.65943","published_at":"2026-04-21T12:55:00Z"},{"value":"0.00499","scoring_system":"epss","scoring_elements":"0.65956","published_at":"2026-04-24T12:55:00Z"},{"value":"0.00499","scoring_system":"epss","scoring_elements":"0.65967","published_at":"2026-04-26T12:55:00Z"},{"value":"0.00499","scoring_system":"epss","scoring_elements":"0.65965","published_at":"2026-04-29T12:55:00Z"},{"value":"0.00499","scoring_system":"epss","scoring_elements":"0.65941","published_at":"2026-05-05T12:55:00Z"},{"value":"0.00499","scoring_system":"epss","scoring_elements":"0.65988","published_at":"2026-05-07T12:55:00Z"},{"value":"0.00499","scoring_system":"epss","scoring_elements":"0.66032","published_at":"2026-05-09T12:55:00Z"},{"value":"0.00499","scoring_system":"epss","scoring_elements":"0.66002","published_at":"2026-05-11T12:55:00Z"},{"value":"0.00499","scoring_system":"epss","scoring_elements":"0.66022","published_at":"2026-05-12T12:55:00Z"},{"value":"0.00499","scoring_system":"epss","scoring_elements":"0.66078","published_at":"2026-05-14T12:55:00Z"},{"value":"0.00499","scoring_system":"epss","scoring_elements":"0.66088","published_at":"2026-05-15T12:55:00Z"},{"value":"0.00499","scoring_system":"epss","scoring_elements":"0.66101","published_at":"2026-05-16T12:55:00Z"}],"url":"https://api.first.org/data/v1/epss?cve=CVE-2018-9860"},{"reference_url":"https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-9860","reference_id":"","reference_type":"","scores":[],"url":"https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2018-9860"}],"fixed_packages":[{"url":"http://public2.vulnerablecode.io/api/packages/1055078?format=json","purl":"pkg:deb/debian/botan@2.9.0-2","is_vulnerable":true,"affected_by_vulnerabilities":[{"vulnerability":"VCID-32jb-t7zq-uyhe"}],"resource_url":"http://public2.vulnerablecode.io/packages/pkg:deb/debian/botan@2.9.0-2"}],"aliases":["CVE-2018-9860"],"risk_score":null,"exploitability":"0.5","weighted_severity":"0.0","resource_url":"http://public2.vulnerablecode.io/vulnerabilities/VCID-bdvc-y1wv-gkcf"},{"url":"http://public2.vulnerablecode.io/api/vulnerabilities/93822?format=json","vulnerability_id":"VCID-wqt2-m3gv-6fgk","summary":"Botan 2.2.0 - 2.4.0 (fixed in 2.5.0) improperly handled wildcard certificates and could accept certain certificates as valid for hostnames when, under RFC 6125 rules, they should not match.
