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-2017-7523 in the wild and no public exploit code.\n\nAffected product: Red Hat, Inc. cygwin. 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-2017-7523/ (Markdown: https://insights.sbomify.com/CVE-2017-7523/index.md)","id":"CVE-2017-7523","markdown":"https://insights.sbomify.com/CVE-2017-7523/index.md","name":"CVE-2017-7523","record":{"aliases":["GHSA-vhqx-rr9r-7jww"],"analysis":{"component_type":"operating_system","fix_type":"upgrade","impacts":["code_execution","denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Cygwin POSIX layer","requires_auth":"none","summary":"Buffer overflow in Cygwin allows attackers to crash processes or execute code with administrative privileges via crafted input.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"cygwin","vendor":"cygwin"}],"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-119","name":"Improper Restriction of Operations within the Bounds of a Memory Buffer"},{"id":"CWE-787","name":"Out-of-bounds Write"}],"description":"Cygwin versions 1.7.2 up to and including 1.8.0 are vulnerable to buffer overflow vulnerability in wcsxfrm/wcsxfrm_l functions resulting into denial-of-service by crashing the process or potential hijack of the process running with administrative privileges triggered by specially crafted input string.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"none_known"},"has_fix":false,"headline":"Memory corruption in cygwin","id":"CVE-2017-7523","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2017"},"n_packages":0,"n_references":1,"next":{"headline":"tpm2-tools versions before 1.1.1 are vulnerable to a password leak due to transmitting password in plaintext from client to server when generating HMAC.","id":"CVE-2017-7524"},"packages":[],"prev":{"headline":"Null dereference in OpenVPN","id":"CVE-2017-7522"},"products":["cygwin"],"published":"2017-07-21","related":[{"cvss_score":9.8,"headline":"Privilege escalation in n/a","id":"CVE-2016-3067","kev_date_added":null,"published":"2017-04-21"}],"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":"2024-09-16","vendors":["Red Hat, Inc."]},"summary":"Buffer overflow in Cygwin allows attackers to crash processes or execute code with administrative privileges via crafted input.","url":"https://insights.sbomify.com/CVE-2017-7523/"}
