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."}], "lastModified": "2023-08-22T14:21:30.250", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:eprosima:fast_dds:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "F15C9800-42FF-4680-91BE-65DD409C2BAD", "versionEndExcluding": "2.6.6", "versionStartIncluding": "2.6.0"}, {"criteria": "cpe:2.3:a:eprosima:fast_dds:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "ACDC404A-DC49-462D-A906-D5B726B5511A", "versionEndExcluding": "2.9.2", "versionStartIncluding": "2.9.0"}, {"criteria": "cpe:2.3:a:eprosima:fast_dds:*:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "F09F92E5-C333-413D-8D93-E310DE1C6873", "versionEndExcluding": "2.10.2", "versionStartIncluding": "2.10.0"}, {"criteria": "cpe:2.3:a:eprosima:fast_dds:2.11.0:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "99CB3D60-0018-4E5E-A54F-6E9098E499AB"}], "operator": "OR"}]}, {"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:o:debian:debian_linux:11.0:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "FA6FEEC2-9F11-4643-8827-749718254FED"}, {"criteria": "cpe:2.3:o:debian:debian_linux:12.0:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "46D69DCC-AE4D-4EA5-861C-D60951444C6C"}], "operator": "OR"}]}], "sourceIdentifier": "security-advisories@github.com"}
