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-2017-7963 in the wild and no public exploit code.\n\nAffected product: Php Php. 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-2017-7963/ (Markdown: https://insights.sbomify.com/CVE-2017-7963/index.md)","id":"CVE-2017-7963","markdown":"https://insights.sbomify.com/CVE-2017-7963/index.md","name":"CVE-2017-7963","record":{"aliases":["GHSA-266p-jjrg-gmfx","UBUNTU-CVE-2017-7963"],"analysis":{"component_type":"library","fix_type":"no_fix_stated","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"PHP GMP interface","requires_auth":"none","summary":"Attackers can cause denial of service via memory consumption and crashes in PHP GMP interfaces by processing long strings.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"php","vendor":"php"}],"cvss":{"score":7.5,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"The GNU Multiple Precision Arithmetic Library (GMP) interfaces for PHP through 7.1.4 allow attackers to cause a denial of service (memory consumption and application crash) via operations on long strings.
