{"id":"CVE-2023-42459","state":"PUBLISHED","title":"Malformed DATA submessage leads to bad-free error in Fast-DDS","description":"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.","publishedAt":"2023-10-16T20:56:04.284Z","updatedAt":"2025-02-13T17:09:23.468Z","severity":{"score":8.6,"label":"High","version":"3.1","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:H","source":"GitHub_M"},"assigner":"GitHub_M","products":["eProsima Fast-DDS"],"affected":[{"vendor":"eProsima","product":"Fast-DDS","versions":[{"version":">= 2.11.0, <= 2.11.1","status":"affected"},{"version":">= 2.10.0, < 2.10.3","status":"affected"},{"version":"< 2.6.7","status":"affected"}]}],"references":["https://github.com/eProsima/Fast-DDS/security/advisories/GHSA-gq8g-fj58-22gm","https://github.com/eProsima/Fast-DDS/issues/3207","https://github.com/eProsima/Fast-DDS/pull/3824","https://www.debian.org/security/2023/dsa-5568"],"weaknesses":["CWE-415","CWE-416","CWE-590"],"ingestedAt":"2026-10-29T20:06:17.512Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2023/42xxx/CVE-2023-42459.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2023-42459","state":"PUBLISHED","datePublished":"2023-10-16T20:56:04.284Z","dateUpdated":"2025-02-13T17:09:23.468Z","assignerShortName":"GitHub_M","assignerOrgId":"a0819718-46f1-4df5-94e2-005712e83aaa","dateReserved":"2023-09-08T20:57:45.574Z"},"containers":{"cna":{"title":"Malformed DATA submessage leads to bad-free error in Fast-DDS","descriptions":[{"lang":"en","value":"Fast DDS is a C++ implementation of the DDS (Data Distribution Service) standard of the OMG (Object Management Group).
