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-2024-1765 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- quiche (crates.io): affected all versions; fixed in 0.19.2\n- quiche (crates.io): affected all versions; fixed in 0.19.2\n- quiche (crates.io): affected from 0.20.0; fixed in 0.20.1\n- quiche (crates.io): affected from 0.20.0; fixed in 0.20.1\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-2024-1765/ (Markdown: https://insights.sbomify.com/CVE-2024-1765/index.md)","id":"CVE-2024-1765","markdown":"https://insights.sbomify.com/CVE-2024-1765/index.md","name":"CVE-2024-1765","record":{"aliases":["GHSA-78wx-jg4j-5j6g"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"QUIC protocol library","requires_auth":"none","summary":"Remote attackers can cause memory exhaustion and denial of service in Cloudflare Quiche by flooding CRYPTO frames after handshake.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cloudflare","cpe":[{"product":"quiche","vendor":"cloudflare"}],"cvss":{"score":5.9,"severity":"medium","source":"cna","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-770","name":"Allocation of Resources Without Limits or Throttling"},{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"Cloudflare Quiche (through version 0.19.1/0.20.0) was affected by an unlimited resource allocation vulnerability causing rapid increase of memory usage of the system running quiche server or client.\nA remote attacker could take advantage of this vulnerability by repeatedly sending an unlimited number of 1-RTT CRYPTO frames after previously completing the QUIC handshake.\nExploitation was possible for the duration of the connection which could be extended by the attacker. \nquiche 0.19.2 and 0.20.1 are the earliest versions containing the fix for this issue.","ecosystems":["crates.io"],"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":"Unlimited resource allocation by QUIC CRYPTO frames flooding in quiche","id":"CVE-2024-1765","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"crates.io","product":null,"products":[],"type":"denial_of_service","year":"2024"},"n_packages":4,"n_references":1,"next":{"headline":"Download Manager \u003c= 3.2.86 - Authenticated (Subscriber+) Stored Self-Based Cross-Site Scripting","id":"CVE-2024-1766"},"packages":[{"ecosystem":"crates.io","fixed":["0.19.2"],"introduced":["0"],"last_affected":[],"package":"quiche","purl":null,"source":"GHSA-78wx-jg4j-5j6g"},{"ecosystem":"crates.io","fixed":["0.19.2"],"introduced":["0"],"last_affected":[],"package":"quiche","purl":"pkg:cargo/quiche","source":"GHSA-78wx-jg4j-5j6g"},{"ecosystem":"crates.io","fixed":["0.20.1"],"introduced":["0.20.0"],"last_affected":[],"package":"quiche","purl":null,"source":"GHSA-78wx-jg4j-5j6g"},{"ecosystem":"crates.io","fixed":["0.20.1"],"introduced":["0.20.0"],"last_affected":[],"package":"quiche","purl":"pkg:cargo/quiche","source":"GHSA-78wx-jg4j-5j6g"}],"prev":{"headline":"Privilege escalation in Server","id":"CVE-2024-1764"},"products":["quiche"],"published":"2024-03-12","related":[{"cvss_score":8.7,"headline":"Infinite loop triggered by connection ID retirement","id":"CVE-2025-7054","kev_date_added":null,"published":"2025-08-07"},{"cvss_score":7.5,"headline":"Resource exhaustion in quiche HTTP/3 and QPACK layers","id":"CVE-2026-12523","kev_date_added":null,"published":"2026-07-14"},{"cvss_score":7.5,"headline":"Incorrect congestion window growth by invalid ACK ranges","id":"CVE-2025-4821","kev_date_added":null,"published":"2025-06-18"},{"cvss_score":5.3,"headline":"Incorrect congestion window growth by optimistic ACK","id":"CVE-2025-4820","kev_date_added":null,"published":"2025-06-18"},{"cvss_score":5.3,"headline":"Unbounded queuing of path validation messages in cloudflare-quiche","id":"CVE-2023-6193","kev_date_added":null,"published":"2023-12-12"},{"cvss_score":3.7,"headline":"Unbounded storage of information related to connection ID retirement, in quiche","id":"CVE-2024-1410","kev_date_added":null,"published":"2024-03-12"}],"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":"no","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2024-08-01","vendors":["Cloudflare"]},"summary":"Remote attackers can cause memory exhaustion and denial of service in Cloudflare Quiche by flooding CRYPTO frames after handshake.","url":"https://insights.sbomify.com/CVE-2024-1765/"}
