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-2024-2511 in the wild and no public exploit code.\n\nAffected product: OpenSSL. 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-2024-2511/ (Markdown: https://insights.sbomify.com/CVE-2024-2511/index.md)","id":"CVE-2024-2511","markdown":"https://insights.sbomify.com/CVE-2024-2511/index.md","name":"CVE-2024-2511","record":{"aliases":["ALPINE-CVE-2024-2511","AZL-39794","AZL-39797","AZL-40192","AZL-42700","AZL-42765","AZL-42949","AZL-47649","AZL-78543","BELL-CVE-2024-2511","CLEANSTART-2026-MP77998","CLSA-2024-1735311149","CLSA-2026-1780513164","DEBIAN-CVE-2024-2511","GHSA-299c-jvhc-gxj8","JLSEC-2026-249","MGASA-2024-0129","OESA-2024-1513","OESA-2024-1531","SUSE-SU-2024:1633-1","SUSE-SU-2024:1634-1","SUSE-SU-2024:1808-1","SUSE-SU-2024:1949-1","UBUNTU-CVE-2024-2511","openSUSE-SU-2024:13937-1","openSUSE-SU-2024:13942-1"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":true,"product_category":"OpenSSL TLS library","requires_auth":"none","summary":"Attackers can cause unbounded memory growth and denial of service in TLSv1.3 servers using non-default SSL_OP_NO_TICKET configuration.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"openssl","cpe":[],"cvss":{"score":5.9,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-1325","name":"Improperly Controlled Sequential Memory Allocation"}],"description":"Issue summary: Some non-default TLS server configurations can cause unbounded\nmemory growth when processing TLSv1.3 sessions\n\nImpact summary: An attacker may exploit certain server configurations to trigger\nunbounded memory growth that would lead to a Denial of Service\n\nThis problem can occur in TLSv1.3 if the non-default SSL_OP_NO_TICKET option is\nbeing used (but not if early_data support is also configured and the default\nanti-replay protection is in use).
