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-2019-3859 in the wild and no public exploit code.\n\nAffected product: Debian Debian Linux. 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-2019-3859/ (Markdown: https://insights.sbomify.com/CVE-2019-3859/index.md)","id":"CVE-2019-3859","markdown":"https://insights.sbomify.com/CVE-2019-3859/index.md","name":"CVE-2019-3859","record":{"aliases":["ALPINE-CVE-2019-3859","DEBIAN-CVE-2019-3859","GHSA-3fjx-35vx-pq97","SUSE-SU-2019:1059-1","SUSE-SU-2019:1060-1","SUSE-SU-2019:14031-1","SUSE-SU-2019:14032-1","UBUNTU-CVE-2019-3859","openSUSE-SU-2019:1291-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"libssh2 library","requires_auth":"none","summary":"A remote attacker compromising an SSH server can cause a denial of service or read client memory via an out-of-bounds read in libssh2.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"debian_linux","vendor":"debian"},{"product":"fedora","vendor":"fedoraproject"},{"product":"libssh2","vendor":"libssh2"},{"product":"ontap_select_deploy_administration_utility","vendor":"netapp"},{"product":"leap","vendor":"opensuse"}],"cvss":{"score":5,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:U/C:L/I:L/A:L","version":"3.0"},"cwes":[{"id":"CWE-125","name":"Out-of-bounds Read"}],"description":"An out of bounds read flaw was discovered in libssh2 before 1.8.1 in the _libssh2_packet_require and _libssh2_packet_requirev functions.
