{"id":"CVE-2023-42459","summary":"Malformed DATA submessage leads to bad-free error in Fast-DDS","details":"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.","aliases":["GHSA-gq8g-fj58-22gm"],"modified":"2026-09-14T03:30:53.585974563Z","published":"2023-10-16T20:56:04.284Z","database_specific":{"cna_assigner":"GitHub_M","cwe_ids":["CWE-415","CWE-416","CWE-590"],"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/42xxx/CVE-2023-42459.json"},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2023/42xxx/CVE-2023-42459.json"},{"type":"ADVISORY","url":"https://github.com/eProsima/Fast-DDS/security/advisories/GHSA-gq8g-fj58-22gm"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2023-42459"},{"type":"ADVISORY","url":"https://www.debian.org/security/2023/dsa-5568"},{"type":"REPORT","url":"https://github.com/eProsima/Fast-DDS/issues/3207"},{"type":"FIX","url":"https://github.com/eProsima/Fast-DDS/pull/3824"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/eprosima/fast-dds","events":[{"introduced":"0"},{"fixed":"125f90341a52d73abcfa5621f9bb51895cf44bbb"},{"introduced":"463d59ca81c7fd732edf45b982a58c0b54fc1da4"},{"fixed":"5ac1dbacc7847f9bc080328930a7a8adcada2fe5"},{"introduced":"64700fcb9058c14e3c7aeee0ec130c47c9824917"},{"last_affected":"4d6d7532cd08dabdeb0134e86227700dbd44125b"}],"database_specific":{"cpe":"cpe:2.3:a:eprosima:fast_dds:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"2.6.7"},{"introduced":"2.10.0"},{"fixed":"2.10.3"},{"introduced":"2.11.0"},{"last_affected":"2.11.1"}],"source":"CPE_RANGE"}}],"versions":["v2.10.1-rc1","v2.10.0-rc1","v2.3.0-1","v2.3.0-api","v2.2.0","v2.1.0","2.0.0-rc","2.0.0-beta","v1.7.2","Discovery-Time_Data_Typing","v1.9.0","v1.9.0-beta-2","v1.9.0-beta","v1.8.0-2","v1.8.0","v1.7.1","v1.7.0","v1.6.0","v1.5.0","v1.4.0","v1.3.0","v1.0.0"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2023-42459.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:H"}]}
