Man-in-the-middle attackers or a malicious server can crash TLS 1.2 clients during a handshake. If an attacker injects a large ticket (more than 256 bytes) into a NewSessionTicket message in a TLS 1.2 handshake, and the client has a non-empty session cache, the session cache frees a pointer that points to unallocated memory, causing the client to crash with a \"free(): invalid pointer\" message. NOTE: It is likely that this is also exploitable during TLS 1.3 handshakes between a client and a malicious server. With TLS 1.3, it is not possible to exploit this as a man-in-the-middle.","state":"PUBLIC","assigner":"cve@mitre.org","published_at":"2022-08-31 18:15:00","updated_at":"2023-03-01 15:51:00"},"problem_types":["CWE-770"],"metrics":[],"references":[{"url":"https://github.com/trailofbits/tlspuffin","name":"https://github.com/trailofbits/tlspuffin","refsource":"MISC","tags":[],"title":"GitHub - trailofbits/tlspuffin: A symbolic-model-guided fuzzer for TLS","mime":"text/html","httpstatus":"200","archivestatus":"200"},{"url":"https://www.wolfssl.com/docs/security-vulnerabilities/","name":"https://www.wolfssl.com/docs/security-vulnerabilities/","refsource":"CONFIRM","tags":[],"title":"wolfSSL Security Vulnerabilities | Documentation – wolfSSL","mime":"text/html","httpstatus":"200","archivestatus":"200"},{"url":"https://blog.trailofbits.com/2023/01/12/wolfssl-vulnerabilities-tlspuffin-fuzzing-ssh/","name":"https://blog.trailofbits.com/2023/01/12/wolfssl-vulnerabilities-tlspuffin-fuzzing-ssh/","refsource":"MISC","tags":[],"title":"Keeping the wolves out of wolfSSL | Trail of Bits Blog","mime":"text/html","httpstatus":"200","archivestatus":"200"},{"url":"http://packetstormsecurity.com/files/170605/wolfSSL-5.3.0-Denial-Of-Service.html","name":"http://packetstormsecurity.com/files/170605/wolfSSL-5.3.0-Denial-Of-Service.html","refsource":"MISC","tags":[],"title":"wolfSSL 5.3.0 Denial Of Service ≈ Packet Storm","mime":"text/html","httpstatus":"200","archivestatus":"404"},{"url":"https://github.com/wolfSSL/wolfssl/releases","name":"https://github.com/wolfSSL/wolfssl/releases","refsource":"MISC","tags":[],"title":"Releases · wolfSSL/wolfssl · GitHub","mime":"text/html","httpstatus":"200","archivestatus":"200"},{"url":"http://seclists.org/fulldisclosure/2023/Jan/8","name":"20230119 wolfSSL 5.3.0: Denial-of-service","refsource":"FULLDISC","tags":[],"title":"Full Disclosure: wolfSSL 5.3.0: Denial-of-service","mime":"text/html","httpstatus":"200","archivestatus":"404"},{"url":"https://github.com/wolfSSL/wolfssl/pull/5476","name":"https://github.com/wolfSSL/wolfssl/pull/5476","refsource":"MISC","tags":[],"title":"Remove WOLFSSL_SESSION_TYPE_REF buffers from WOLFSSL_SESSION by julek-wolfssl · Pull Request #5476 · wolfSSL/wolfssl · GitHub","mime":"text/html","httpstatus":"200","archivestatus":"404"},{"url":"https://www.cve.org/CVERecord?id=CVE-2022-38153","name":"CVE Program record","refsource":"CVE.ORG","tags":["canonical"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2022-38153","name":"NVD vulnerability detail","refsource":"NVD","tags":["canonical","analysis"]}],"affected":[],"timeline":[],"solutions":[],"workarounds":[],"exploits":[],"credits":[],"nvd_cpes":[{"cve_year":"2022","cve_id":"38153","vulnerable":"1","versionEndIncluding":"","cpe1":"cpe","cpe2":"2.3","cpe3":"a","cpe4":"wolfssl","cpe5":"wolfssl","cpe6":"5.3.0","cpe7":"*","cpe8":"*","cpe9":"*","cpe10":"*","cpe11":"*","cpe12":"*","cpe13":"*"}],"vendor_comments":[],"enrichments":{"kev":null,"epss":null,"legacy_qids":[{"cve":"CVE-2022-38153","qid":"182584","title":"Debian Security Update for wolfssl (CVE-2022-38153)"}]},"source_records":{"cve_program":{"CVE_data_meta":{"ASSIGNER":"cve@mitre.org","ID":"CVE-2022-38153","STATE":"PUBLIC"},"affects":{"vendor":{"vendor_data":[{"product":{"product_data":[{"product_name":"n/a","version":{"version_data":[{"version_value":"n/a"}]}}]},"vendor_name":"n/a"}]}},"data_format":"MITRE","data_type":"CVE","data_version":"4.0","description":{"description_data":[{"lang":"eng","value":"An issue was discovered in wolfSSL before 5.5.0 (when --enable-session-ticket is used); however, only version 5.3.0 is exploitable.
