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-2015-5312 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- nokogiri (RubyGems): affected from 1.6.0; fixed in 1.6.7.1\n- nokogiri (RubyGems): affected from 1.6.0; fixed in 1.6.7.1\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-2015-5312/ (Markdown: https://insights.sbomify.com/CVE-2015-5312/index.md)","id":"CVE-2015-5312","markdown":"https://insights.sbomify.com/CVE-2015-5312/index.md","name":"CVE-2015-5312","record":{"aliases":["DEBIAN-CVE-2015-5312","ECHO-ad99-83b5-cd1c","GHSA-xjqg-9jvg-fgx2","UBUNTU-CVE-2015-5312"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"XML parsing library","requires_auth":"none","summary":"Attackers can cause denial of service via CPU consumption by sending crafted XML data to applications using the vulnerable libxml2 library.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"iphone_os","vendor":"apple"},{"product":"mac_os_x","vendor":"apple"},{"product":"tvos","vendor":"apple"},{"product":"watchos","vendor":"apple"},{"product":"ubuntu_linux","vendor":"canonical"},{"product":"debian_linux","vendor":"debian"},{"product":"icewall_federation_agent","vendor":"hp"},{"product":"icewall_file_manager","vendor":"hp"},{"product":"enterprise_linux_desktop","vendor":"redhat"},{"product":"enterprise_linux_hpc_node","vendor":"redhat"},{"product":"enterprise_linux_server","vendor":"redhat"},{"product":"enterprise_linux_workstation","vendor":"redhat"},{"product":"libxml2","vendor":"xmlsoft"}],"cvss":{"score":7.1,"severity":"high","source":"nvd","vector":"AV:N/AC:M/Au:N/C:N/I:N/A:C","version":"2.0"},"cwes":[{"id":"CWE-399","name":null}],"description":"The xmlStringLenDecodeEntities function in parser.c in libxml2 before 2.9.3 does not properly prevent entity expansion, which allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted XML data, a different vulnerability than CVE-2014-3660.","ecosystems":["RubyGems"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Nokogiri subject to DoS via libxml2 vulnerability","id":"CVE-2015-5312","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"RubyGems","product":"apple:iphone_os","products":["apple:iphone_os","apple:mac_os_x","apple:tvos","apple:watchos","canonical:ubuntu_linux","debian:debian_linux","redhat:enterprise_linux_desktop","redhat:enterprise_linux_hpc_node","redhat:enterprise_linux_server","redhat:enterprise_linux_workstation","xmlsoft:libxml2"],"type":"denial_of_service","year":"2015"},"n_packages":2,"n_references":25,"next":{"headline":"Path traversal in n/a","id":"CVE-2015-5313"},"packages":[{"ecosystem":"RubyGems","fixed":["1.6.7.1"],"introduced":["1.6.0"],"last_affected":[],"package":"nokogiri","purl":null,"source":"GHSA-xjqg-9jvg-fgx2"},{"ecosystem":"RubyGems","fixed":["1.6.7.1"],"introduced":["1.6.0"],"last_affected":[],"package":"nokogiri","purl":"pkg:gem/nokogiri","source":"GHSA-xjqg-9jvg-fgx2"}],"prev":{"headline":"Denial of service in n/a","id":"CVE-2015-5311"},"products":["n/a"],"published":"2015-12-15","related":[{"cvss_score":8.8,"headline":"Apple iOS WebKit Buffer Overflow","id":"CVE-2021-30666","kev_date_added":"2021-11-03","published":"2021-09-08"},{"cvss_score":8.8,"headline":"Apple iOS WebKit Memory Corruption","id":"CVE-2021-30761","kev_date_added":"2021-11-03","published":"2021-09-08"},{"cvss_score":8.8,"headline":"Apple iOS WebKit Use-After-Free","id":"CVE-2021-30762","kev_date_added":"2021-11-03","published":"2021-09-08"},{"cvss_score":8.8,"headline":"Apple iOS Webkit Memory Corruption","id":"CVE-2016-4657","kev_date_added":"2022-05-24","published":"2016-08-25"},{"cvss_score":7.8,"headline":"Apple Multiple Products Memory Corruption","id":"CVE-2019-7286","kev_date_added":"2022-05-23","published":"2019-12-18"},{"cvss_score":7.8,"headline":"Apple iOS Memory Corruption","id":"CVE-2019-7287","kev_date_added":"2022-05-23","published":"2019-12-18"},{"cvss_score":7.8,"headline":"Apple Multiple Products Use-After-Free","id":"CVE-2019-8605","kev_date_added":"2022-06-27","published":"2019-12-18"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"US public information, NVD API terms","name":"NVD"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-08-06","vendors":["n/a"]},"summary":"Attackers can cause denial of service via CPU consumption by sending crafted XML data to applications using the vulnerable libxml2 library.","url":"https://insights.sbomify.com/CVE-2015-5312/"}
