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-2017-8786 in the wild and no public exploit code.\n\nAffected product: n/a. 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-2017-8786/ (Markdown: https://insights.sbomify.com/CVE-2017-8786/index.md)","id":"CVE-2017-8786","markdown":"https://insights.sbomify.com/CVE-2017-8786/index.md","name":"CVE-2017-8786","record":{"aliases":["DEBIAN-CVE-2017-8786","GHSA-5w9f-5949-m2r9","UBUNTU-CVE-2017-8786"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"PCRE2 library","requires_auth":"none","summary":"A heap-based buffer overflow in PCRE2 allows remote attackers to cause denial of service or potentially execute code via crafted regular expressions.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"pcre2","vendor":"pcre"}],"cvss":{"score":9.8,"severity":"critical","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"pcre2test.c in PCRE2 10.23 allows remote attackers to cause a denial of service (heap-based buffer overflow) or possibly have unspecified other impact via a crafted regular expression.","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":"Memory corruption in n/a","id":"CVE-2017-8786","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2017"},"n_packages":0,"n_references":5,"next":{"headline":"Memory corruption in n/a","id":"CVE-2017-8787"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2017-8785"},"products":["n/a"],"published":"2017-05-05","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2017-8399","kev_date_added":null,"published":"2017-05-01"},{"cvss_score":7.5,"headline":"Integer overflow in n/a","id":"CVE-2022-41409","kev_date_added":null,"published":"2023-07-18"},{"cvss_score":7.4,"headline":"Use after free in PCRE2","id":"CVE-2026-89161","kev_date_added":null,"published":"2026-09-11"},{"cvss_score":6.9,"headline":"PCRE2: heap-buffer-overflow read in match_ref due to missing boundary restoration in SCS","id":"CVE-2025-58050","kev_date_added":null,"published":"2025-08-27"},{"cvss_score":6.5,"headline":"Integer overflow in PCRE2","id":"CVE-2026-89158","kev_date_added":null,"published":"2026-09-11"},{"cvss_score":5.7,"headline":"Memory corruption in PCRE2","id":"CVE-2026-89157","kev_date_added":null,"published":"2026-09-11"}],"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":"2024-08-05","vendors":["n/a"]},"summary":"A heap-based buffer overflow in PCRE2 allows remote attackers to cause denial of service or potentially execute code via crafted regular expressions.","url":"https://insights.sbomify.com/CVE-2017-8786/"}
