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-2020-10543 in the wild and no public exploit code.\n\nAffected product: Fedoraproject Fedora. 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-2020-10543/ (Markdown: https://insights.sbomify.com/CVE-2020-10543/index.md)","id":"CVE-2020-10543","markdown":"https://insights.sbomify.com/CVE-2020-10543/index.md","name":"CVE-2020-10543","record":{"aliases":["ALPINE-CVE-2020-10543","CLEANSTART-2026-RP32633","CLSA-2021-1632328264","CLSA-2021-1634922942","DEBIAN-CVE-2020-10543","UBUNTU-CVE-2020-10543"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Perl programming language","requires_auth":"none","summary":"A heap-based buffer overflow in Perl on 32-bit platforms allows attackers to execute arbitrary code or cause denial of service via nested regular expression quantifiers.","user_interaction":"not_required","vuln_class":"integer_overflow"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"fedora","vendor":"fedoraproject"},{"product":"leap","vendor":"opensuse"},{"product":"communications_billing_and_revenue_management","vendor":"oracle"},{"product":"communications_diameter_signaling_router","vendor":"oracle"},{"product":"communications_eagle_application_processor","vendor":"oracle"},{"product":"communications_eagle_lnp_application_processor","vendor":"oracle"},{"product":"communications_lsms","vendor":"oracle"},{"product":"communications_offline_mediation_controller","vendor":"oracle"},{"product":"communications_performance_intelligence_center","vendor":"oracle"},{"product":"communications_pricing_design_center","vendor":"oracle"},{"product":"configuration_manager","vendor":"oracle"},{"product":"enterprise_manager_base_platform","vendor":"oracle"},{"product":"sd-wan_edge","vendor":"oracle"},{"product":"tekelec_platform_distribution","vendor":"oracle"},{"product":"perl","vendor":"perl"}],"cvss":{"score":8.2,"severity":"high","source":"nvd","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:L/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-190","name":"Integer Overflow or Wraparound"}],"description":"Perl before 5.30.3 on 32-bit platforms allows a heap-based buffer overflow because nested regular expression quantifiers have an integer overflow.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":true,"headline":"Integer overflow in n/a","id":"CVE-2020-10543","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"fedoraproject:fedora","products":["fedoraproject:fedora","opensuse:leap","oracle:communications_billing_and_revenue_management","oracle:communications_diameter_signaling_router","oracle:enterprise_manager_base_platform"],"type":"integer_overflow","year":"2020"},"n_packages":0,"n_references":14,"next":{"headline":"Cross-site Scripting in PrimeFaces","id":"CVE-2020-10544"},"packages":[],"prev":{"headline":"Code injection in n/a","id":"CVE-2020-10541"},"products":["n/a"],"published":"2020-06-05","related":[{"cvss_score":9.8,"headline":"PHP-CGI OS Command Injection","id":"CVE-2024-4577","kev_date_added":"2024-06-12","published":"2024-06-09"},{"cvss_score":9.8,"headline":"Grafana Authentication Bypass","id":"CVE-2021-39226","kev_date_added":"2022-08-25","published":"2021-10-05"},{"cvss_score":9.8,"headline":"VMware ESXi and Horizon DaaS OpenSLP Heap-Based Buffer Overflow","id":"CVE-2019-5544","kev_date_added":"2021-11-03","published":"2019-12-06"},{"cvss_score":9.6,"headline":"Google Chromium V8 Type Confusion","id":"CVE-2024-4947","kev_date_added":"2024-05-20","published":"2024-05-15"},{"cvss_score":9.6,"headline":"Google Chromium Visuals Use-After-Free","id":"CVE-2024-4671","kev_date_added":"2024-05-13","published":"2024-05-09"},{"cvss_score":9.6,"headline":"Google Chromium Mojo Insufficient Data Validation","id":"CVE-2022-3075","kev_date_added":"2022-09-08","published":"2022-09-26"},{"cvss_score":9.6,"headline":"Google Chromium Indexed DB API Use-After-Free","id":"CVE-2021-30633","kev_date_added":"2021-11-03","published":"2021-10-08"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2026-10-14","vendors":["n/a"]},"summary":"A heap-based buffer overflow in Perl on 32-bit platforms allows attackers to execute arbitrary code or cause denial of service via nested regular expression quantifiers.","url":"https://insights.sbomify.com/CVE-2020-10543/"}
