CVE-2019-17211

An integer overflow was discovered in the CoAP library in Arm Mbed OS 5.14.0. The function sncoapbuildercalcneededpacketdatasize2 is used to calculate the required memory for the CoAP message from the sncoaphdrs data structure. Both returnedbytecount and srccoapmsgptr-payloadlen are of type...

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...
