Heap overflow in push_back_helper due to a CDR message
Résumé
Heap overflow in push_back_helper due to a CDR message
Description d'origine
La description telle que publiée par la source (souvent en anglais).
eprosima Fast DDS is a C++ implementation of the Data Distribution Service standard of the Object Management Group. Prior to versions 2.11.1, 2.10.2, 2.9.2, and 2.6.6, heap can be overflowed by providing a PID_PROPERTY_LIST parameter that contains a CDR string with length larger than the size of actual content. In eprosima::fastdds::dds::ParameterPropertyList_t::push_back_helper, memcpy is called to first copy the octet'ized length and then to copy the data into properties_.data. At the second memcpy, both data and size can be controlled by anyone that sends the CDR string to the discovery multicast port. This can remotely crash any Fast-DDS process. Versions 2.11.1, 2.10.2, 2.9.2, and 2.6.6 contain a patch for this issue.
