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

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...
