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-2023-45802 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- apache (Bitnami): affected from 2.4.17; fixed in 2.4.58\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-2023-45802/ (Markdown: https://insights.sbomify.com/CVE-2023-45802/index.md)","id":"CVE-2023-45802","markdown":"https://insights.sbomify.com/CVE-2023-45802/index.md","name":"CVE-2023-45802","record":{"aliases":["ALPINE-CVE-2023-45802","AZL-31611","AZL-43531","AZL-45147","BELL-CVE-2023-45802","BIT-apache-2023-45802","CLEANSTART-2026-UI43314","CLSA-2026-1778873714","DEBIAN-CVE-2023-45802","GHSA-m4mp-v249-x3mh","OESA-2023-1803","SUSE-SU-2024:3949-1","SUSE-SU-2024:3961-1","SUSE-SU-2024:3962-1","SUSE-SU-2024:3999-1","UBUNTU-CVE-2023-45802"],"analysis":{"component_type":"server_software","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Apache HTTP Server","requires_auth":"none","summary":"An attacker can cause memory exhaustion in Apache HTTP Server by repeatedly resetting HTTP/2 streams, leading to denial of service.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"apache","cpe":[{"product":"http_server","vendor":"apache"},{"product":"debian_linux","vendor":"debian"},{"product":"fedora","vendor":"fedoraproject"}],"cvss":{"score":5.9,"severity":"medium","source":"nvd","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-404","name":"Improper Resource Shutdown or Release"}],"description":"When a HTTP/2 stream was reset (RST frame) by a client, there was a time window were the request's memory resources were not reclaimed immediately. Instead, de-allocation was deferred to connection close. A client could send new requests and resets, keeping the connection busy and open and causing the memory footprint to keep on growing. On connection close, all resources were reclaimed, but the process might run out of memory before that.\n\nThis was found by the reporter during testing of CVE-2023-44487 (HTTP/2 Rapid Reset Exploit) with their own test client. During \"normal\" HTTP/2 use, the probability to hit this bug is very low. The kept memory would not become noticeable before the connection closes or times out.\n\nUsers are recommended to upgrade to version 2.4.58, which fixes the issue.","ecosystems":["Bitnami","SUSE:Enterprise Storage 7.1","SUSE:Linux Enterprise High Performance Computing 15 SP2-LTSS","SUSE:Linux Enterprise High Performance Computing 15 SP3-LTSS","SUSE:Linux
