{"id":"CVE-2026-70461","summary":"rsync 3.2.5 \u003c 3.5.0 Heap Out-of-Bounds Write via files-from Entry","details":"rsync 3.2.5 before 3.5.0 contains a heap out-of-bounds write vulnerability that allows remote unauthenticated attackers to write one attacker-controlled byte past the end of a heap allocation by supplying a crafted files-from entry. Attackers can trigger the vulnerability against a read-only rsync daemon module by providing a files-from entry containing both an interior and trailing backslash, causing the add_implied_include() function to under-count the trailing backslash when sizing the destination buffer.","aliases":["GHSA-jhxm-j4mq-3fj4"],"modified":"2026-09-15T16:56:52.537427874Z","published":"2026-08-13T14:42:49.726Z","related":["ALSA-2026:67462","ALSA-2026:67463","SUSE-SU-2026:23253-1","SUSE-SU-2026:23254-1","SUSE-SU-2026:23289-1","SUSE-SU-2026:23323-1","SUSE-SU-2026:3634-1","SUSE-SU-2026:3657-1","openSUSE-SU-2026:21650-1"],"database_specific":{"osv_generated_from":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/70xxx/CVE-2026-70461.json","cna_assigner":"VulnCheck","cwe_ids":["CWE-787"]},"references":[{"type":"ADVISORY","url":"https://github.com/CVEProject/cvelistV5/tree/main/cves/2026/70xxx/CVE-2026-70461.json"},{"type":"ADVISORY","url":"https://github.com/RsyncProject/rsync/releases/tag/v3.5.0"},{"type":"ADVISORY","url":"https://github.com/RsyncProject/rsync/security/advisories/GHSA-jhxm-j4mq-3fj4"},{"type":"ADVISORY","url":"https://nvd.nist.gov/vuln/detail/CVE-2026-70461"},{"type":"ADVISORY","url":"https://www.vulncheck.com/advisories/rsync-heap-out-of-bounds-write-via-files-from-entry"},{"type":"PACKAGE","url":"https://github.com/RsyncProject/rsync"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://git.samba.org/rsync.git/","events":[{"introduced":"0e10163a9d984a8858f7d83b5c7b46889536aa96"},{"fixed":"471e17dc0d68233db84db11be82c9f62f4661214"}],"database_specific":{"cpe":"cpe:2.3:a:samba:rsync:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"3.2.5"},{"fixed":"3.5.0"}],"source":"CPE_RANGE"}},{"type":"GIT","repo":"https://github.com/rsyncproject/rsync","events":[{"introduced":"0e10163a9d984a8858f7d83b5c7b46889536aa96"},{"fixed":"471e17dc0d68233db84db11be82c9f62f4661214"}],"database_specific":{"cpe":"cpe:2.3:a:samba:rsync:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"3.2.5"},{"last_affected":"3.4.4"},{"fixed":"3.5.0"}],"source":["AFFECTED_FIELD","CPE_RANGE","REFERENCES"]}}],"versions":["v3.4.3","v3.4","v3.2.7","v3.4.1","v3.4.2","v3.4.0","v3.3.0","v3.3.0pre1","v3.2.7pre1","v3.2.6","v3.2.5"],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2026-70461.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V4","score":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:N/VC:N/VI:L/VA:H/SC:N/SI:N/SA:N"}]}
