An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-70462 in the wild and no public exploit code.\n\nAffected product: RsyncProject rsync. No package-level version data is available, so check the vendor advisory linked from the reference page.\n\nTask:\n1. Search the dependency manifests and lockfiles (for example package.json, package-lock.json, requirements.txt, poetry.lock, uv.lock, pom.xml, build.gradle, go.mod, Cargo.lock, Gemfile.lock) and any Dockerfiles for the affected packages, including transitive dependencies.\n2. If an affected version is in use, upgrade it to the fixed version for its release line with the project's package manager, so the lockfile is regenerated. Prefer the smallest upgrade that fixes it.\n3. If there is no fix, or the upgrade would break the build, do not guess: explain the risk and the safest workaround instead.\n4. Run the tests and summarise what changed and why.\n5. If nothing in the project is affected, say so and change nothing.\n\nReference: https://insights.sbomify.com/CVE-2026-70462/ (Markdown: https://insights.sbomify.com/CVE-2026-70462/index.md)","id":"CVE-2026-70462","markdown":"https://insights.sbomify.com/CVE-2026-70462/index.md","name":"CVE-2026-70462","record":{"aliases":["ALPINE-CVE-2026-70462","AZL-95840","BELL-CVE-2026-70462","DEBIAN-CVE-2026-70462","ECHO-255d-4439-03d3","GHSA-j9wh-5jmp-2m64","ROOT-OS-DEBIAN-11-CVE-2026-70462","UBUNTU-CVE-2026-70462"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"rsync file transfer","requires_auth":"none","summary":"Attackers can cause resource exhaustion in rsync daemons by sending crafted messages that disable connection timeouts, requiring an upgrade to fix.","user_interaction":"required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"VulnCheck","cpe":[],"cvss":{"score":7.1,"severity":"high","source":"cna","vector":"CVSS:4.0/AV:N/AC:L/AT:N/PR:N/UI:P/VC:N/VI:N/VA:H/SC:N/SI:N/SA:N","version":"4.0"},"cwes":[{"id":"CWE-835","name":"Loop with Unreachable Exit Condition"},{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"rsync 3.1.0 before 3.5.0 contains a signed integer overflow vulnerability in the I/O timeout implementation that allows attackers to permanently disable connection timeouts by injecting MSG_IO_TIMEOUT messages carrying non-positive (zero or negative) values.
