Summary
eprosima Fast DDS prior to versions 2.11.1, 2.10.2, 2.9.2, and 2.6.6 is vulnerable to heap overflow caused by the PID_PROPERTY_LIST parameter containing a CDR string longer than the actual content size. This vulnerability can lead to remote crashes of any Fast-DDS process.
Risk Assessment
Organizations using vulnerable versions of Fast DDS may experience remote crashes of their processes, leading to service interruptions and potential financial losses.
Recommendation
It is recommended to upgrade to versions 2.11.1, 2.10.2, 2.9.2, or 2.6.6, which contain a patch for this vulnerability.

Original NVD description (English source)
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.
