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."}],"affected":[{"vendor":"n/a","product":"n/a","versions":[{"version":"n/a","status":"affected"}]}],"references":[{"url":"https://github.com/wolfSSL/wolfssl/releases"},{"url":"https://www.wolfssl.com/docs/security-vulnerabilities/"},{"url":"https://github.com/wolfSSL/wolfssl/pull/5476"},{"url":"https://github.com/trailofbits/tlspuffin"},{"name":"20230119 wolfSSL 5.3.0: Denial-of-service","tags":["mailing-list"],"url":"http://seclists.org/fulldisclosure/2023/Jan/8"},{"url":"http://packetstormsecurity.com/files/170605/wolfSSL-5.3.0-Denial-Of-Service.html"},{"url":"https://blog.trailofbits.com/2023/01/12/wolfssl-vulnerabilities-tlspuffin-fuzzing-ssh/"}],"problemTypes":[{"descriptions":[{"type":"text","lang":"en","description":"n/a"}]}]},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-03T10:45:52.834Z"},"title":"CVE Program Container","references":[{"url":"https://github.com/wolfSSL/wolfssl/releases","tags":["x_transferred"]},{"url":"https://www.wolfssl.com/docs/security-vulnerabilities/","tags":["x_transferred"]},{"url":"https://github.com/wolfSSL/wolfssl/pull/5476","tags":["x_transferred"]},{"url":"https://github.com/trailofbits/tlspuffin","tags":["x_transferred"]},{"name":"20230119 wolfSSL 5.3.0: Denial-of-service","tags":["mailing-list","x_transferred"],"url":"http://seclists.org/fulldisclosure/2023/Jan/8"},{"url":"http://packetstormsecurity.com/files/170605/wolfSSL-5.3.0-Denial-Of-Service.html","tags":["x_transferred"]},{"url":"https://blog.trailofbits.com/2023/01/12/wolfssl-vulnerabilities-tlspuffin-fuzzing-ssh/","tags":["x_transferred"]}]}]}}
