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-2017-7526 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-2017-7526/ (Markdown: https://insights.sbomify.com/CVE-2017-7526/index.md)","id":"CVE-2017-7526","markdown":"https://insights.sbomify.com/CVE-2017-7526/index.md","name":"CVE-2017-7526","record":{"aliases":["ALPINE-CVE-2017-7526","AZL-41702","DEBIAN-CVE-2017-7526","DLA-1015-1","DLA-1080-1","DSA-3901-1","DSA-3960-1","GHSA-f2v5-c455-qhg2","MGASA-2017-0213","MGASA-2017-0235","SUSE-SU-2017:1793-1","SUSE-SU-2017:1794-1","SUSE-SU-2017:1866-1","UBUNTU-CVE-2017-7526","USN-3733-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":false,"product_category":"libgcrypt crypto library","requires_auth":"none","summary":"A cache side-channel attack in libgcrypt allows local attackers to recover RSA private keys by running arbitrary software on the target hardware.","user_interaction":"required","vuln_class":"information_disclosure"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"ubuntu_linux","vendor":"canonical"},{"product":"debian_linux","vendor":"debian"},{"product":"libgcrypt","vendor":"gnupg"}],"cvss":{"score":6.1,"severity":"medium","source":"cna","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:R/S:C/C:H/I:N/A:N","version":"3.0"},"cwes":[{"id":"CWE-310","name":null},{"id":"CWE-200","name":"Exposure of Sensitive Information to an Unauthorized Actor"}],"description":"libgcrypt before version 1.7.8 is vulnerable to a cache side-channel attack resulting into a complete break of RSA-1024 while using the left-to-right method for computing the sliding-window expansion.
