An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link."},"fix_prompt":"Check this codebase for CVE-2021-33657 and fix it if it is affected.\n\nWhat it is: CVE-2021-33657 is a high-severity memory corruption vulnerability in SDL2, published on 1 Apr 2022. An attacker can exploit it over the internet without logging in, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2021-33657 in the wild and no public exploit code.\n\nAffected product: SDL2. 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-2021-33657/ (Markdown: https://insights.sbomify.com/CVE-2021-33657/index.md)","id":"CVE-2021-33657","markdown":"https://insights.sbomify.com/CVE-2021-33657/index.md","name":"CVE-2021-33657","record":{"aliases":["DEBIAN-CVE-2021-33657","GHSA-9276-2w6v-wx4c","JLSEC-2026-364","MGASA-2022-0326","OESA-2022-1592","SUSE-SU-2022:1218-1","SUSE-SU-2022:1313-1","UBUNTU-CVE-2021-33657","USN-5398-1","openSUSE-SU-2024:11984-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"SDL2 graphics library","requires_auth":"none","summary":"A heap overflow in SDL2 allows attackers to execute arbitrary code or cause denial of service via malicious BMP files.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"openEuler","cpe":[{"product":"simple_directmedia_layer","vendor":"libsdl"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"There is a heap overflow problem in video/SDL_pixels.c in SDL (Simple DirectMedia Layer) 2.x to 2.0.18 versions.
