{"id":"UBUNTU-CVE-2024-12084","details":"A heap-based buffer overflow flaw was found in the rsync daemon. This issue is due to improper handling of attacker-controlled checksum lengths (s2length) in the code. When MAX_DIGEST_LEN exceeds the fixed SUM_LENGTH (16 bytes), an attacker can write out of bounds in the sum2 buffer.","modified":"2026-01-30T00:56:21.844126Z","published":"2025-01-09T00:00:00Z","related":["USN-7206-1","USN-7206-3"],"upstream":["CVE-2024-12084"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2024-12084"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2024-12084"},{"type":"REPORT","url":"https://kb.cert.org/vince/comm/case/2083/"},{"type":"REPORT","url":"https://github.com/RsyncProject/rsync/commit/0902b52f6687b1f7952422080d50b93108742e53"},{"type":"REPORT","url":"https://github.com/RsyncProject/rsync/commit/66015104257ab2b9b28b21411abf0b25a979a954"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-7206-1"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-7206-3"}],"affected":[{"package":{"name":"rsync","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/rsync@3.2.7-0ubuntu0.22.04.3?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.2.7-0ubuntu0.22.04.3"}]}],"versions":["3.2.3-4ubuntu1","3.2.3-4ubuntu2","3.2.3-8ubuntu1","3.2.3-8ubuntu2","3.2.3-8ubuntu3","3.2.3-8ubuntu3.1","3.2.7-0ubuntu0.22.04.2"],"ecosystem_specific":{"priority_reason":"Possible remote code execution or denial of service","availability":"No subscription required","binaries":[{"binary_name":"rsync","binary_version":"3.2.7-0ubuntu0.22.04.3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-12084.json"}},{"package":{"name":"rsync","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/rsync@3.2.7-1ubuntu1.1?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.2.7-1ubuntu1.1"}]}],"versions":["3.2.7-1","3.2.7-1build1","3.2.7-1build2","3.2.7-1ubuntu1"],"ecosystem_specific":{"priority_reason":"Possible remote code execution or denial of service","availability":"No subscription required","binaries":[{"binary_name":"rsync","binary_version":"3.2.7-1ubuntu1.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-12084.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:H/I:H/A:H"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},{"type":"Ubuntu","score":"high"}]}
