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-2024-34249 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- pywasm3 (PyPI): affected all versions up to 0.5.0; no fix listed\n- pywasm3 (PyPI): affected all versions up to 0.5.0; no fix listed\n- pywasm3 (PyPI): affected all versions up to 0.5.0; no fix listed\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-2024-34249/ (Markdown: https://insights.sbomify.com/CVE-2024-34249/index.md)","id":"CVE-2024-34249","markdown":"https://insights.sbomify.com/CVE-2024-34249/index.md","name":"CVE-2024-34249","record":{"aliases":["GHSA-mq9p-qw76-q6h7","PYSEC-2024-308"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"WebAssembly runtime library","requires_auth":"none","summary":"A heap buffer overflow in the wasm3 library allows attackers to cause a segmentation fault and denial of service.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"wasm3","vendor":"wasm3_project"}],"cvss":{"score":9.8,"severity":"critical","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"wasm3 v0.5.0 was discovered to contain a heap buffer overflow which leads to segmentation fault via the function \"DeallocateSlot\" in wasm3/source/m3_compile.c.","ecosystems":["PyPI"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"pywasm3 contains a heap buffer overflow which leads to segmentation fault","id":"CVE-2024-34249","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"PyPI","product":null,"products":[],"type":"memory_corruption","year":"2024"},"n_packages":3,"n_references":1,"next":{"headline":"Memory corruption in n/a","id":"CVE-2024-34250"},"packages":[{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":["0.5.0"],"package":"pywasm3","purl":null,"source":"GHSA-mq9p-qw76-q6h7"},{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":["0.5.0"],"package":"pywasm3","purl":"pkg:pypi/pywasm3","source":"GHSA-mq9p-qw76-q6h7"},{"ecosystem":"PyPI","fixed":[],"introduced":["0"],"last_affected":["0.5.0"],"package":"pywasm3","purl":"pkg:pypi/pywasm3","source":"PYSEC-2024-308"}],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2024-34246"},"products":["n/a"],"published":"2024-05-06","related":[{"cvss_score":8.4,"headline":"pywasm3 has an Invalid Memory Read, Leading to DoS and Potential Code Execution","id":"CVE-2024-27528","kev_date_added":null,"published":"2024-11-08"},{"cvss_score":8.4,"headline":"wasm3 uncontrolled memory allocation vulnerability","id":"CVE-2024-27529","kev_date_added":null,"published":"2024-11-08"},{"cvss_score":8.4,"headline":"pywasm3 contains a Use-After-Free in ForEachModule","id":"CVE-2024-27530","kev_date_added":null,"published":"2024-11-08"},{"cvss_score":7.8,"headline":"Buffer overflow in wasm3","id":"CVE-2022-28990","kev_date_added":null,"published":"2022-05-20"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2024-27527","kev_date_added":null,"published":"2024-11-08"},{"cvss_score":7.5,"headline":"Memory corruption in n/a","id":"CVE-2024-34246","kev_date_added":null,"published":"2024-05-06"}],"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":"CC BY 4.0","name":"PyPA Advisory Database","prefix":"PYSEC"},{"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":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2024-08-02","vendors":["n/a"]},"summary":"A heap buffer overflow in the wasm3 library allows attackers to cause a segmentation fault and denial of service.","url":"https://insights.sbomify.com/CVE-2024-34249/"}
