It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2023-39562 exists.\n\nAffected product: Gpac Gpac. 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-2023-39562/ (Markdown: https://insights.sbomify.com/CVE-2023-39562/index.md)","id":"CVE-2023-39562","markdown":"https://insights.sbomify.com/CVE-2023-39562/index.md","name":"CVE-2023-39562","record":{"aliases":["DEBIAN-CVE-2023-39562","GHSA-wmx6-799c-66vc","UBUNTU-CVE-2023-39562"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"GPAC multimedia library","requires_auth":"none","summary":"Attackers can cause a denial of service in GPAC by supplying a crafted file that triggers a heap-use-after-free in the bitstream alignment function.","user_interaction":"required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"gpac","vendor":"gpac"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:N/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-416","name":"Use After Free"}],"description":"GPAC v2.3-DEV-rev449-g5948e4f70-master was discovered to contain a heap-use-after-free via the gf_bs_align function at bitstream.c.
