{"id":"UBUNTU-CVE-2023-42459","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.","modified":"2026-05-20T16:13:50.384451635Z","published":"2023-10-16T21:15:00Z","upstream":["CVE-2023-42459"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2023-42459"},{"type":"REPORT","url":"https://github.com/eProsima/Fast-DDS/security/advisories/GHSA-gq8g-fj58-22gm"},{"type":"REPORT","url":"https://github.com/eProsima/Fast-DDS/issues/3207"},{"type":"REPORT","url":"https://github.com/eProsima/Fast-DDS/pull/3824"},{"type":"REPORT","url":"https://github.com/eProsima/Fast-DDS/commit/1e978c6f3d0ca1df6b323b37fd4902b0762ececb"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2023-42459"}],"affected":[{"package":{"name":"fastdds","ecosystem":"Ubuntu:Pro:22.04:LTS","purl":"pkg:deb/ubuntu/fastdds?arch=source&distro=esm-apps%2Fjammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.1.0+ds-9","2.4.1+ds-1","2.5.0+ds-3","2.5.0+ds-3ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_version":"2.5.0+ds-3ubuntu0.1~esm1","binary_name":"fastdds-tools"},{"binary_name":"libfastrtps2.5","binary_version":"2.5.0+ds-3ubuntu0.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-42459.json"}},{"package":{"name":"fastdds","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/fastdds?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["2.10.1+ds-3","2.11.2+ds-6","2.11.2+ds-6ubuntu1","2.11.2+ds-6.1build2","2.11.2+ds-6.1build3"],"ecosystem_specific":{"binaries":[{"binary_name":"fastdds-tools","binary_version":"2.11.2+ds-6.1build3"},{"binary_version":"2.11.2+ds-6.1build3","binary_name":"libfastrtps2.11t64"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-42459.json"}},{"package":{"name":"fastdds","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/fastdds?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.1.2+ds-1","3.1.2+ds-1build1"],"ecosystem_specific":{"binaries":[{"binary_version":"3.1.2+ds-1build1","binary_name":"fastdds-tools"},{"binary_name":"libfastdds3.1","binary_version":"3.1.2+ds-1build1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-42459.json"}},{"package":{"name":"fastdds","ecosystem":"Ubuntu:26.04:LTS","purl":"pkg:deb/ubuntu/fastdds?arch=source&distro=resolute"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["3.1.2+ds-1build1","3.3.0+ds-3ubuntu1"],"ecosystem_specific":{"binaries":[{"binary_version":"3.3.0+ds-3ubuntu1","binary_name":"fastdds-tools"},{"binary_name":"libfastdds3.3","binary_version":"3.3.0+ds-3ubuntu1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2023/UBUNTU-CVE-2023-42459.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:H"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"type":"Ubuntu","score":"medium"}]}
