Silent element-count truncation via 32-bit bit-length overflow in packed-bit vector views
A weakness in the BSON library's handling of a specialized binary vector data type allows an arithmetic wraparound when computing the number of elements described by an oversized attacker-supplied value. On builds where the platform word size is 32 bits, an a…

Out-of-bounds read in SCRAM response parsing in MongoDB C Driver
An out-of-bounds read in SCRAM authentication response parsing in the MongoDB C Driver can read one byte beyond a fixed-size buffer when processing a malformed server-final message. A server or network intermediary able to provide this message before server-s…

libmongoc SCRAM client nonce-validation bypass
A flaw in libmongoc's SCRAM authentication implementation caused the client to continue the authentication handshake and transmit the client proof even when a nonce mismatch was detected in the server's first message. An unauthorized party with a man-in-the-m…

Heap overflow via truncated base64 encoding of binary fields in length-limited JSON output
A memory-handling error in the BSON-to-JSON conversion helpers of the MongoDB C Driver can write a small number of bytes past the end of a heap buffer when a binary field is encoded and the output is cut short at a caller-configured length limit. A party who …

Heap-buffer-over-read in _mongoc_http_send via strstr on non-null-terminated buffer
A compromised third party cloud server or man-in-the-middle attacker could send a malformed HTTP response and cause a crash in applications using the MongoDB C driver.
