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."}],"source":{"advisory":"GHSA-j297-rg6j-m7hx","discovery":"UNKNOWN"}},"adp":[{"providerMetadata":{"orgId":"af854a3a-2127-422b-91ae-364da2661108","shortName":"CVE","dateUpdated":"2024-08-02T18:18:10.179Z"},"title":"CVE Program Container","references":[{"name":"https://github.com/eProsima/Fast-DDS/security/advisories/GHSA-j297-rg6j-m7hx","tags":["x_refsource_CONFIRM","x_transferred"],"url":"https://github.com/eProsima/Fast-DDS/security/advisories/GHSA-j297-rg6j-m7hx"},{"name":"https://github.com/eProsima/Fast-DDS/commit/349227005827e8a67a0406b823138b5068cc47dc","tags":["x_refsource_MISC","x_transferred"],"url":"https://github.com/eProsima/Fast-DDS/commit/349227005827e8a67a0406b823138b5068cc47dc"},{"url":"https://www.debian.org/security/2023/dsa-5481","tags":["x_transferred"]}]},{"metrics":[{"other":{"type":"ssvc","content":{"timestamp":"2024-10-10T14:22:11.929256Z","id":"CVE-2023-39946","options":[{"Exploitation":"poc"},{"Automatable":"yes"},{"Technical Impact":"partial"}],"role":"CISA Coordinator","version":"2.0.3"}}}],"title":"CISA ADP Vulnrichment","providerMetadata":{"orgId":"134c704f-9b21-4f2e-91b3-4a467353bcc0","shortName":"CISA-ADP","dateUpdated":"2024-10-10T14:22:26.307Z"}}]}}
