Hi,

The following vulnerability was published for fastdds.

CVE-2023-42459[0]:
| 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.
