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-2023-24534 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- golang (Bitnami): affected all versions; fixed in 1.19.8, 1.20.3\n- stdlib (Go): affected all versions; fixed in 1.19.8, 1.20.3\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-2023-24534/ (Markdown: https://insights.sbomify.com/CVE-2023-24534/index.md)","id":"CVE-2023-24534","markdown":"https://insights.sbomify.com/CVE-2023-24534/index.md","name":"CVE-2023-24534","record":{"aliases":["AZL-25990","AZL-26027","AZL-37414","AZL-37484","AZL-52878","AZL-79066","AZL-98766","BIT-golang-2023-24534","DEBIAN-CVE-2023-24534","GHSA-8v5j-pwr7-w5f8","GO-2023-1704","MINI-hvrm-hh7q-vg33","OESA-2023-1822","OESA-2023-1823","OESA-2023-1824","UBUNTU-CVE-2023-24534"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Go standard library","requires_auth":"none","summary":"An attacker can cause memory exhaustion and denial of service in Go applications by sending crafted HTTP or MIME headers that trigger excessive memory allocation.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Go","cpe":[{"product":"go","vendor":"golang"}],"cvss":{"score":7.5,"severity":"high","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-400","name":"Uncontrolled Resource Consumption"}],"description":"HTTP and MIME header parsing can allocate large amounts of memory, even when parsing small inputs, potentially leading to a denial of service. Certain unusual patterns of input data can cause the common function used to parse HTTP and MIME headers to allocate substantially more memory than required to hold the parsed headers. An attacker can exploit this behavior to cause an HTTP server to allocate large amounts of memory from a small request, potentially leading to memory exhaustion and a denial of service.
