An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2013-0339 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-2013-0339/ (Markdown: https://insights.sbomify.com/CVE-2013-0339/index.md)","id":"CVE-2013-0339","markdown":"https://insights.sbomify.com/CVE-2013-0339/index.md","name":"CVE-2013-0339","record":{"aliases":["DEBIAN-CVE-2013-0339","GHSA-4qgp-72gr-jfg9"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["data_read","denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"XML parsing library","requires_auth":"none","summary":"Remote attackers can cause denial of service, read arbitrary files, or send HTTP requests via crafted XML due to improper external entity handling in libxml2.","user_interaction":"not_required","vuln_class":"xxe"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"ubuntu_linux","vendor":"canonical"},{"product":"debian_linux","vendor":"debian"},{"product":"linux_enterprise_server","vendor":"suse"},{"product":"libxml2","vendor":"xmlsoft"}],"cvss":{"score":6.8,"severity":"medium","source":"nvd","vector":"AV:N/AC:M/Au:N/C:P/I:P/A:P","version":"2.0"},"cwes":[{"id":"CWE-264","name":null}],"description":"libxml2 through 2.9.1 does not properly handle external entities expansion unless an application developer uses the xmlSAX2ResolveEntity or xmlSetExternalEntityLoader function, which allows remote attackers to cause a denial of service (resource consumption), send HTTP requests to intranet servers, or read arbitrary files via a crafted XML document, aka an XML External Entity (XXE) issue.
