| CVE-2020-16150 | 3 Arm, Debian, Fedoraproject | 3 Mbed Tls, Debian Linux, Fedora | 2024-02-28 | 2.1 LOW | 5.5 MEDIUM |
| A Lucky 13 timing side channel in mbedtls_ssl_decrypt_buf in library/ssl_msg.c in Trusted Firmware Mbed TLS through 2.23.0 allows an attacker to recover secret key information. This affects CBC mode because of a computed time difference based on a padding length. | |||||
| CVE-2020-12883 | 1 Arm | 1 Mbed Os | 2024-02-28 | 6.4 MEDIUM | 9.1 CRITICAL |
| Buffer over-reads were discovered in the CoAP library in Arm Mbed OS 5.15.3. The CoAP parser is responsible for parsing received CoAP packets. The function sn_coap_parser_options_parse() parses CoAP input linearly using a while loop. Once an option is parsed in a loop, the current point (*packet_data_pptr) is increased correspondingly. The pointer is restricted by the size of the received buffer, as well as by the option delta and option length bytes. The actual input packet length is not verified against the number of bytes read when processing the option extended delta and the option extended length. Moreover, the calculation of the message_left variable, in the case of non-extended option deltas, is incorrect and indicates more data left for processing than provided in the function input. All of these lead to heap-based or stack-based memory location read access that is outside of the intended boundary of the buffer. Depending on the platform-specific memory management mechanisms, it can lead to processing of unintended inputs or system memory access violation errors. | |||||
| CVE-2020-12886 | 1 Arm | 1 Mbed Os | 2024-02-28 | 6.4 MEDIUM | 9.1 CRITICAL |
| A buffer over-read was discovered in the CoAP library in Arm Mbed OS 5.15.3. The CoAP parser is responsible for parsing received CoAP packets. The function sn_coap_parser_options_parse() parses the CoAP packet header starting from the message token. The length of the token in the received message is provided in the first byte parsed by the sn_coap_parser_options_parse() function. The length encoded in the message is not validated against the actual input buffer length before accessing the token. As a result, memory access outside of the intended boundary of the buffer may occur. | |||||
| CVE-2020-12884 | 1 Arm | 1 Mbed Os | 2024-02-28 | 6.4 MEDIUM | 9.1 CRITICAL |
| A buffer over-read was discovered in the CoAP library in Arm Mbed OS 5.15.3. The CoAP parser is responsible for parsing received CoAP packets. The function sn_coap_parser_options_parse_multiple_options() parses CoAP options that may occur multiple consecutive times in a single packet. While processing the options, packet_data_pptr is accessed after being incremented by option_len without a prior out-of-bounds memory check. The temp_parsed_uri_query_ptr is validated for a correct range, but the range valid for temp_parsed_uri_query_ptr is derived from the amount of allocated heap memory, not the actual input size. Therefore the check of temp_parsed_uri_query_ptr may be insufficient for safe access to the area pointed to by packet_data_pptr. As a result, access to a memory area outside of the intended boundary of the packet buffer is made. | |||||

| Arm Mbed TLS before 2.16.5 allows attackers to obtain sensitive information (an RSA private key) by measuring cache usage during an import. | |||||
| CVE-2020-13844 | 2 Arm, Opensuse | 15 Cortex-a32, Cortex-a32 Firmware, Cortex-a34 and 12 more | 2024-02-28 | 2.1 LOW | 5.5 MEDIUM |
| Arm Armv8-A core implementations utilizing speculative execution past unconditional changes in control flow may allow unauthorized disclosure of information to an attacker with local user access via a side-channel analysis, aka "straight-line speculation." | |||||
| CVE-2020-12885 | 1 Arm | 1 Mbed Os | 2024-02-28 | 7.8 HIGH | 7.5 HIGH |
| An infinite loop was discovered in the CoAP library in Arm Mbed OS 5.15.3. The CoAP parser is responsible for parsing received CoAP packets. The function sn_coap_parser_options_parse_multiple_options() parses CoAP options in a while loop. This loop's exit condition is computed using the previously allocated heap memory required for storing the result of parsing multiple options. If the input heap memory calculation results in zero bytes, the loop exit condition is never met and the loop is not terminated. As a result, the packet parsing function never exits, leading to resource consumption. | |||||
| CVE-2019-18222 | 3 Arm, Debian, Fedoraproject | 4 Mbed Crypto, Mbed Tls, Debian Linux and 1 more | 2024-02-28 | 1.9 LOW | 4.7 MEDIUM |
| The ECDSA signature implementation in ecdsa.c in Arm Mbed Crypto 2.1 and Mbed TLS through 2.19.1 does not reduce the blinded scalar before computing the inverse, which allows a local attacker to recover the private key via side-channel attacks. | |||||
| CVE-2019-17210 | 1 Arm | 2 Mbed-mqtt, Mbed-os | 2024-02-28 | 5.0 MEDIUM | 7.5 HIGH |
| A denial-of-service issue was discovered in the MQTT library in Arm Mbed OS 2017-11-02. The function readMQTTLenString() is called by the function MQTTDeserialize_publish() to get the length and content of the MQTT topic name. In the function readMQTTLenString(), mqttstring->lenstring.len is a part of user input, which can be manipulated. An attacker can simply change it to a larger value to invalidate the if statement so that the statements inside the if statement are skipped, letting the value of mqttstring->lenstring.data default to zero. Later, curn is accessed, which points to mqttstring->lenstring.data. On an Arm Cortex-M chip, the value at address 0x0 is actually the initialization value for the MSP register. It is highly dependent on the actual firmware. Therefore, the behavior of the program is unpredictable from this time on. | |||||
