CVE-2019-17211

CVE-2019-17211 affects Arm Mbed OS 5.14.0 CoAP library. The overflow occurs in sn_coap_builder_calc_needed_packet_data_size_2 when computing memory for a CoAP message: returned_byte_count and payload_len are uint16_t and their sum can wrap around, causing insufficient buffer space. Documents conf...

CVE-2019-17212

Buffer overflows were discovered in the CoAP library in Arm Mbed OS 5.14.0. The CoAP parser is responsible for parsing received CoAP packets. The function sncoapparseroptionsparse parses CoAP input linearly using a while loop. Once an option is parsed in a loop, the current point packetdatapptr i...

CVE-2019-17212

Arm Mbed OS CoAP library (mbed-coap) version 5.14.0 contains a buffer overflow in the CoAP parser sn_coap_parser_options_parse(), where pointer bounds are not consistently enforced inside loops, enabling heap- or stack-based overflows when processing crafted CoAP packets. The root cause is lack o...
