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-2012-2739 in the wild and no public exploit code.\n\nAffected product: Oracle Jdk. 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-2012-2739/ (Markdown: https://insights.sbomify.com/CVE-2012-2739/index.md)","id":"CVE-2012-2739","markdown":"https://insights.sbomify.com/CVE-2012-2739/index.md","name":"CVE-2012-2739","record":{"aliases":["GHSA-g4rj-4w28-44fg"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Java runtime library","requires_auth":"none","summary":"Attackers can cause denial of service via CPU exhaustion by triggering predictable hash collisions in Java hash tables.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"jdk","vendor":"oracle"},{"product":"jre","vendor":"oracle"},{"product":"openjdk","vendor":"oracle"}],"cvss":{"score":5,"severity":"medium","source":"nvd","vector":"AV:N/AC:L/Au:N/C:N/I:N/A:P","version":"2.0"},"cwes":[{"id":"CWE-310","name":null}],"description":"Oracle Java SE before 7 Update 6, and OpenJDK 7 before 7u6 build 12 and 8 before build 39, computes hash values without restricting the ability to trigger hash collisions predictably, which allows context-dependent attackers to cause a denial of service (CPU consumption) via crafted input to an application that maintains a hash table.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":null,"headline":"Denial of service in n/a","id":"CVE-2012-2739","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"oracle:jdk","products":["oracle:jdk","oracle:jre","oracle:openjdk"],"type":"denial_of_service","year":"2012"},"n_packages":0,"n_references":8,"next":{"headline":"SQL injection in n/a","id":"CVE-2012-2740"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2012-2738"},"products":["n/a"],"published":"2012-11-28","related":[{"cvss_score":9.8,"headline":"Oracle Java SE Runtime Environment (JRE) Arbitrary Code Execution","id":"CVE-2012-4681","kev_date_added":"2022-03-03","published":"2012-08-28"},{"cvss_score":9.8,"headline":"Oracle Java SE Runtime Environment (JRE) Arbitrary Code Execution","id":"CVE-2012-1723","kev_date_added":"2022-03-03","published":"2012-06-16"},{"cvss_score":10,"headline":"Deserialization in n/a","id":"CVE-2015-4805","kev_date_added":null,"published":"2015-10-21"},{"cvss_score":10,"headline":"Other in n/a","id":"CVE-2015-4835","kev_date_added":null,"published":"2015-10-21"},{"cvss_score":10,"headline":"Other in n/a","id":"CVE-2015-4843","kev_date_added":null,"published":"2015-10-21"},{"cvss_score":10,"headline":"Other in n/a","id":"CVE-2015-4844","kev_date_added":null,"published":"2015-10-21"},{"cvss_score":10,"headline":"Other in n/a","id":"CVE-2015-4860","kev_date_added":null,"published":"2015-10-21"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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 exhaustion by triggering predictable hash collisions in Java hash tables.","url":"https://insights.sbomify.com/CVE-2012-2739/"}
