An issue was discovered in Contiki-NG tinyDTLS versions through 2018-08-30. A buffer over-read exists in the dtls_sha256_update function. This bug allows remote attackers to cause a denial of service (crash) and possibly read sensitive information by sending a malformed packet with an over-large fragment length field, due to servers incorrectly handling malformed packets.

An issue was discovered in Contiki-NG tinyDTLS versions through 2018-08-30. DTLS servers allow remote attackers to reuse the same epoch number within two times the TCP maximum segment lifetime, which is prohibited in RFC6347. This vulnerability allows remote attackers to obtain sensitive application (data of connected clients).

An issue was discovered in Contiki-NG tinyDTLS versions through 2018-08-30. An assertion failure in check_certificate_request() causes the server to exit unexpectedly, resulting in a denial of service.

An issue was discovered in Contiki-NG tinyDTLS versions through 2018-08-30. Incorrect handling of over-large packets in dtls_ccm_decrypt_message() causes a buffer over-read that can expose sensitive information.

An issue was discovered in Contiki-NG tinyDTLS versions through 2018-08-30. 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.

An issue was discovered in Contiki-NG tinyDTLS versions through 2018-08-30. 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.

An issue was discovered in Contiki-NG tinyDTLS versions 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.

A Cross-Frame Scripting vulnerability has been found on Plone CMS affecting version below 6.0.5. An attacker could store a malicious URL to be opened by an administrator and execute a malicios iframe element.

Redis raft versions master-1b8bd86 to master-7b46079 were discovered to contain an ODR violation via the component hiredisAllocFns at /opt/fs/redisraft/deps/hiredis/alloc.c.
