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-2012-0955 in the wild and no public exploit code.\n\nAffected product: Canonical software-properties. 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-2012-0955/ (Markdown: https://insights.sbomify.com/CVE-2012-0955/index.md)","id":"CVE-2012-0955","markdown":"https://insights.sbomify.com/CVE-2012-0955/index.md","name":"CVE-2012-0955","record":{"aliases":["DEBIAN-CVE-2012-0955","GHSA-47v9-xw5c-g56f"],"analysis":{"component_type":"operating_system","fix_type":"upgrade","impacts":["data_read","security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"Ubuntu software-properties","requires_auth":"none","summary":"Attackers can intercept traffic via man-in-the-middle attacks due to improper TLS certificate validation in Ubuntu's software-properties tool.","user_interaction":"required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"canonical","cpe":[{"product":"software-properties","vendor":"canonical"}],"cvss":{"score":6.8,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:U/C:H/I:H/A:N","version":"3.1"},"cwes":[{"id":"CWE-295","name":"Improper Certificate Validation"}],"description":"software-properties was vulnerable to a person-in-the-middle attack due to incorrect TLS certificate validation in softwareproperties/ppa.py. software-properties didn't check TLS certificates under python2 and only checked certificates under python3 if a valid certificate bundle was provided.
