| CVE-2021-42147 | 1 Contiki-ng | 1 Tinydtls | 2024-11-21 | N/A | 9.1 CRITICAL |
| Buffer over-read vulnerability in the dtls_sha256_update function in Contiki-NG tinyDTLS through master branch 53a0d97 allows remote attackers to cause a denial of service via crafted data packet. | |||||
| CVE-2021-42145 | 1 Contiki-ng | 1 Tinydtls | 2024-11-21 | N/A | 7.5 HIGH |
| An assertion failure discovered in in check_certificate_request() in Contiki-NG tinyDTLS through master branch 53a0d97 allows attackers to cause a denial of service. | |||||
| CVE-2021-42143 | 1 Contiki-ng | 1 Tinydtls | 2024-11-21 | N/A | 9.1 CRITICAL |
| An issue was discovered in Contiki-NG tinyDTLS through master branch 53a0d97. An infinite loop bug exists during the handling of a ClientHello handshake message. This bug allows remote attackers to cause a denial of service by sending a malformed ClientHello handshake message with an odd length of cipher suites, which triggers an infinite loop (consuming all resources) and a buffer over-read that can disclose sensitive information. | |||||
| CVE-2021-42142 | 1 Contiki-ng | 1 Tinydtls | 2024-11-21 | N/A | 9.8 CRITICAL |
| An issue was discovered in Contiki-NG tinyDTLS through master branch 53a0d97. DTLS servers mishandle the early use of a large epoch number. This vulnerability allows remote attackers to cause a denial of service and false-positive packet drops. | |||||
| CVE-2021-42141 | 1 Contiki-ng | 1 Tinydtls | 2024-11-21 | N/A | 9.8 CRITICAL |
| An issue was discovered in Contiki-NG tinyDTLS through 2018-08-30. One incorrect handshake could complete with different epoch numbers in the packets Client_Hello, Client_key_exchange, and Change_cipher_spec, which may cause denial of service. | |||||
