In OpenDDS through 3.27, there is a segmentation fault for a DataWriter with a large value of resource_limits.max_samples. NOTE: the vendor's position is that the product is not designed to handle a max_samples value that is too large for the amount of memory on the system.

Fast DDS is a C++ implementation of the DDS (Data Distribution Service) standard of the OMG (Object Management Group). In affected versions specific DATA submessages can be sent to a discovery locator which may trigger a free error. This can remotely crash any Fast-DDS process. The call to free() could potentially leave the pointer in the attackers control which could lead to a double free. This issue has been addressed in versions 2.12.0, 2.11.3, 2.10.3, and 2.6.7. Users are advised to upgrade. There are no known workarounds for this vulnerability.

eprosima Fast DDS is a C++ implementation of the Data Distribution Service standard of the Object Management Group. Prior to versions 2.9.1 and 2.6.5, improper validation of sequence numbers may lead to remotely reachable assertion failure. This can remotely crash any Fast-DDS process. Versions 2.9.1 and 2.6.5 contain a patch for this issue.

eprosima Fast DDS is a C++ implementation of the Data Distribution Service standard of the Object Management Group. Prior to versions 2.10.0 and 2.6.5, the `BadParamException` thrown by Fast CDR is not caught in Fast DDS. This can remotely crash any Fast DDS process. Versions 2.10.0 and 2.6.5 contain a patch for this issue.

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.

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.

eprosima Fast DDS is a C++ implementation of the Data Distribution Service standard of the Object Management Group. Prior to versions 2.11.0, 2.10.2, 2.9.2, and 2.6.5, a data submessage sent to PDP port raises unhandled `BadParamException` in fastcdr, which in turn crashes fastdds. Versions 2.11.0, 2.10.2, 2.9.2, and 2.6.5 contain a patch for this issue.

eprosima Fast DDS is a C++ implementation of the Data Distribution Service standard of the Object Management Group. Prior to versions 2.10.0, 2.9.2, and 2.6.5, a malformed GAP submessage can trigger assertion failure, crashing FastDDS. Version 2.10.0, 2.9.2, and 2.6.5 contain a patch for this issue.

OpenDDS is an open source C++ implementation of the Object Management Group (OMG) Data Distribution Service (DDS). OpenDDS crashes while parsing a malformed `PID_PROPERTY_LIST` in a DATA submessage during participant discovery. Attackers can remotely crash OpenDDS processes by sending a DATA submessage containing the malformed parameter to the known multicast port. This issue has been addressed in version 3.25. Users are advised to upgrade. There are no known workarounds for this vulnerability.

Buffer Copy without Checking Size of Input ('Classic Buffer Overflow') vulnerability in Mitsubishi Electric Corporation MELSEC iQ-F Series CPU modules and MELSEC iQ-R Series CPU modules allows a remote unauthenticated attacker to cause a denial of service (DoS) condition or execute malicious code on a target product by sending specially crafted packets. A system reset of the product is required for recovery from a denial of service (DoS) condition and malicious code execution.
