{"id":"CVE-2022-39173","details":"In wolfSSL before 5.5.1, malicious clients can cause a buffer overflow during a TLS 1.3 handshake. This occurs when an attacker supposedly resumes a previous TLS session. During the resumption Client Hello a Hello Retry Request must be triggered. Both Client Hellos are required to contain a list of duplicate cipher suites to trigger the buffer overflow. In total, two Client Hellos have to be sent: one in the resumed session, and a second one as a response to a Hello Retry Request message.","modified":"2026-08-12T03:51:19.731266975Z","published":"2022-09-29T00:00:00Z","database_specific":{"cna_assigner":"mitre","osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/39xxx/CVE-2022-39173.json"},"references":[{"type":"WEB","url":"http://packetstormsecurity.com/files/169600/wolfSSL-Buffer-Overflow.html"},{"type":"WEB","url":"https://www.wolfssl.com/docs/security-vulnerabilities/"},{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2022/39xxx/CVE-2022-39173.json"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2022-39173"},{"type":"PACKAGE","url":"https://github.com/wolfSSL/wolfssl/releases"},{"type":"ARTICLE","url":"http://seclists.org/fulldisclosure/2022/Oct/24"},{"type":"ARTICLE","url":"https://blog.trailofbits.com/2023/01/12/wolfssl-vulnerabilities-tlspuffin-fuzzing-ssh/"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/wolfssl/wolfssl","events":[{"introduced":"0"},{"fixed":"f1e2165c591f074feb47872a8ff712713ec411e1"}],"database_specific":{"extracted_events":[{"introduced":"0"},{"fixed":"5.5.1"}],"source":["DESCRIPTION","CPE_RANGE"],"cpe":"cpe:2.3:a:wolfssl:wolfssl:*:*:*:*:*:*:*:*"}}],"versions":["WCv5.0-RC12","WCv5.0-RC11","WCv5.0-RC10","v5.5.0-stable","v5.4.0-stable","v5.3.0-stable","v5.2.0-stable","v5.1.0-stable","v5.0.0-stable","WCv5.0-RC9","v4.8.0-stable","v4.7.1r","v4.7.0-stable","v4.6.0-stable","v4.5.0-stable","v4.4.0-stable","v4.3.0-stable","v4.2.0c","v4.2.0-stable","v4.1.0-stable","v4.0.0-stable","list","v3.15.7-stable","v3.15.6","v3.15.5a","v3.15.5-stable","WCv4-rng-stable","v3.15.3-stable","l","v3.15.0-stable","v3.14.4","v3.14.2","v3.14.0b","v3.14.0a","v3.14.0-stable","v3.13.3","v3.13.2","v3.13.0-stable","v3.12.2-stable","v3.12.0-stable","v3.11.1-tls13-beta","v3.11.0-stable","v3.10.3","v3.10.2-stable","v3.10.0a","v3.10.0-stable","v3.9.10b","v3.9.10-stable","v3.9.8","v3.9.6w","v3.9.6","v3.9.1","v3.9.0","v3.8.0","v3.7.3","v3.7.1","v3.7.0","v3.6.9","v3.6.8","v3.4.6","v3.4.2","v3.4.0","v3.3.3","v3.3.0","v3.2.6","v3.2.4","v3.2.0","v2.9.4","v2.9.2","v2.9.1","v0.5","v2.9.0","v2.8.6","v2.8.5a","v2.8.5","v2.8.4","v2.8.3","v2.8.2","v2.8.0","v2.7.2","v2.7.0","v2.6.2","v2.6.0","v2.4.7","v2.4.6","v2.4.2","v2.0.8","v2.0.6","v2.0.3","v2.0.2","v2.0rc3","v2.0rc2b","v2.0rc2","v2.0rc1","v1.9.0","v1.8.8.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2022-39173.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"}]}
