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, even after the fix at commit 3492270, malformed
PID_PROPERTY_LIST parameters cause heap overflow at a different program
counter. 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.
