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.","publishedAt":"2022-08-31T00:00:00.000Z","updatedAt":"2024-08-03T10:45:52.834Z","severity":null,"assigner":"mitre","products":["n/a n/a"],"affected":[{"vendor":"n/a","product":"n/a","versions":[{"version":"n/a","status":"affected"}]}],"references":["https://github.com/wolfSSL/wolfssl/releases","https://www.wolfssl.com/docs/security-vulnerabilities/","https://github.com/wolfSSL/wolfssl/pull/5476","https://github.com/trailofbits/tlspuffin","http://seclists.org/fulldisclosure/2023/Jan/8","http://packetstormsecurity.com/files/170605/wolfSSL-5.3.0-Denial-Of-Service.html","https://blog.trailofbits.com/2023/01/12/wolfssl-vulnerabilities-tlspuffin-fuzzing-ssh/"],"weaknesses":[],"ingestedAt":"2026-10-29T19:50:26.582Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2022/38xxx/CVE-2022-38153.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2022-38153","state":"PUBLISHED","datePublished":"2022-08-31T00:00:00.000Z","dateUpdated":"2024-08-03T10:45:52.834Z","assignerShortName":"mitre","assignerOrgId":"8254265b-2729-46b6-b9e3-3dfca2d5bfca","dateReserved":"2022-08-11T00:00:00.000Z"},"containers":{"cna":{"descriptions":[{"lang":"en","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.
