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-2017-12883 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-2017-12883/ (Markdown: https://insights.sbomify.com/CVE-2017-12883/index.md)","id":"CVE-2017-12883","markdown":"https://insights.sbomify.com/CVE-2017-12883/index.md","name":"CVE-2017-12883","record":{"aliases":["ALPINE-CVE-2017-12883","CLEANSTART-2026-YO60841","DEBIAN-CVE-2017-12883","GHSA-h435-qr7v-xh34","UBUNTU-CVE-2017-12883"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Perl programming language","requires_auth":"none","summary":"Remote attackers can cause information disclosure or application crashes in Perl via a crafted regular expression with an invalid escape sequence.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"perl","vendor":"perl"}],"cvss":{"score":9.1,"severity":"critical","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:H","version":"3.0"},"cwes":[{"id":"CWE-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"}],"description":"Buffer overflow in the S_grok_bslash_N function in regcomp.c in Perl 5 before 5.24.3-RC1 and 5.26.x before 5.26.1-RC1 allows remote attackers to disclose sensitive information or cause a denial of service (application crash) via a crafted regular expression with an invalid '\\N{U+...}' escape.","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-2017-12883","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2017"},"n_packages":0,"n_references":10,"next":{"headline":"Information disclosure in n/a","id":"CVE-2017-12884"},"packages":[],"prev":{"headline":"Spring Batch Admin vulnerable to Stored Cross-site scripting (XSS) in the file upload functionality","id":"CVE-2017-12882"},"products":["n/a"],"published":"2017-09-19","related":[{"cvss_score":9.8,"headline":"Supply chain in perl","id":"CVE-2026-4176","kev_date_added":null,"published":"2026-03-29"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2022-48522","kev_date_added":null,"published":"2023-08-22"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2017-12814","kev_date_added":null,"published":"2017-09-27"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2015-8608","kev_date_added":null,"published":"2017-02-07"},{"cvss_score":9.1,"headline":"Integer overflow in perl:perl","id":"CVE-2026-13221","kev_date_added":null,"published":"2026-07-13"},{"cvss_score":8.4,"headline":"Integer overflow in perl:perl","id":"CVE-2026-57432","kev_date_added":null,"published":"2026-07-13"}],"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":"Remote attackers can cause information disclosure or application crashes in Perl via a crafted regular expression with an invalid escape sequence.","url":"https://insights.sbomify.com/CVE-2017-12883/"}
