{"id":"UBUNTU-CVE-2024-56169","details":"A validation integrity issue was discovered in Fort through 1.6.4 before 2.0.0. RPKI Relying Parties (such as Fort) are supposed to maintain a backup cache of the remote RPKI data. This can be employed as a fallback in case a new fetch fails or yields incorrect files. However, the product currently uses its cache merely as a bandwidth saving tool (because fetching is performed through deltas). If a fetch fails midway or yields incorrect files, there is no viable fallback. This leads to incomplete route origin validation data.","modified":"2026-01-20T18:02:03.037868Z","published":"2024-12-18T05:15:00Z","upstream":["CVE-2024-56169"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2024-56169"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2024-56169"},{"type":"REPORT","url":"https://github.com/NICMx/FORT-validator/issues/82"},{"type":"REPORT","url":"https://nicmx.github.io/FORT-validator/CVE.html"}],"affected":[{"package":{"name":"fort-validator","ecosystem":"Ubuntu:Pro:20.04:LTS","purl":"pkg:deb/ubuntu/fort-validator@1.2.0-1ubuntu0.1~esm1?arch=source&distro=esm-apps/focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.1.1-2","1.1.2-1","1.1.3-1","1.2.0-1","1.2.0-1ubuntu0.1~esm1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.2.0-1ubuntu0.1~esm1","binary_name":"fort-validator"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-56169.json"}},{"package":{"name":"fort-validator","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/fort-validator@1.5.3-1ubuntu0.1?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.5.1-1","1.5.2-1","1.5.3-1","1.5.3-1build1","1.5.3-1ubuntu0.1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.5.3-1ubuntu0.1","binary_name":"fort-validator"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-56169.json"}},{"package":{"name":"fort-validator","ecosystem":"Ubuntu:Pro:24.04:LTS","purl":"pkg:deb/ubuntu/fort-validator@1.6.1-1ubuntu0.1~esm2?arch=source&distro=esm-apps/noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.5.4-1","1.6.1-1","1.6.1-1build2","1.6.1-1build3","1.6.1-1ubuntu0.1~esm2"],"ecosystem_specific":{"binaries":[{"binary_version":"1.6.1-1ubuntu0.1~esm2","binary_name":"fort-validator"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-56169.json"}},{"package":{"name":"fort-validator","ecosystem":"Ubuntu:25.10","purl":"pkg:deb/ubuntu/fort-validator@1.6.6-1build1?arch=source&distro=questing"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.6.6-1","1.6.6-1build1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.6.6-1build1","binary_name":"fort-validator"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-56169.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:N"},{"type":"Ubuntu","score":"medium"}]}
