It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2018-0495 in the wild and no public exploit code.\n\nAffected product: Canonical Ubuntu 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-2018-0495/ (Markdown: https://insights.sbomify.com/CVE-2018-0495/index.md)","id":"CVE-2018-0495","markdown":"https://insights.sbomify.com/CVE-2018-0495/index.md","name":"CVE-2018-0495","record":{"aliases":["ALPINE-CVE-2018-0495","DEBIAN-CVE-2018-0495","DLA-1405-1","DSA-4231-1","GHSA-q2v2-pgm4-m8c8","MGASA-2018-0301","MGASA-2018-0306","MGASA-2019-0038","SUSE-SU-2018:1993-1","SUSE-SU-2018:2089-1","SUSE-SU-2018:2452-2","UBUNTU-CVE-2018-0495","USN-3689-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Libgcrypt crypto library","requires_auth":"low_privilege","summary":"Attackers with local or co-tenant access can recover ECDSA private keys via memory-cache side-channel attacks in Libgcrypt.","user_interaction":"not_required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"debian","cpe":[{"product":"ubuntu_linux","vendor":"canonical"},{"product":"debian_linux","vendor":"debian"},{"product":"libgcrypt","vendor":"gnupg"},{"product":"traffic_director","vendor":"oracle"},{"product":"ansible_tower","vendor":"redhat"},{"product":"enterprise_linux_desktop","vendor":"redhat"},{"product":"enterprise_linux_server","vendor":"redhat"},{"product":"enterprise_linux_workstation","vendor":"redhat"}],"cvss":{"score":4.7,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N","version":"3.0"},"cwes":[{"id":"CWE-203","name":"Observable Discrepancy"}],"description":"Libgcrypt before 1.7.10 and 1.8.x before 1.8.3 allows a memory-cache side-channel attack on ECDSA signatures that can be mitigated through the use of blinding during the signing process in the _gcry_ecc_ecdsa_sign function in cipher/ecc-ecdsa.c, aka the Return Of the Hidden Number Problem or ROHNP.
