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-2017-5581 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-2017-5581/ (Markdown: https://insights.sbomify.com/CVE-2017-5581/index.md)","id":"CVE-2017-5581","markdown":"https://insights.sbomify.com/CVE-2017-5581/index.md","name":"CVE-2017-5581","record":{"aliases":["DEBIAN-CVE-2017-5581","GHSA-q2c6-v9x6-qvr4"],"analysis":{"component_type":"desktop_application","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"TigerVNC client","requires_auth":"none","summary":"A remote VNC server can execute arbitrary code on a TigerVNC client by sending a malformed RRE message with out-of-bounds subrectangles.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"tigervnc","vendor":"tigervnc"}],"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":"Buffer overflow in the ModifiablePixelBuffer::fillRect function in TigerVNC before 1.7.1 allows remote servers to execute arbitrary code via an RRE message with subrectangle outside framebuffer boundaries.","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-2017-5581","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2017"},"n_packages":0,"n_references":9,"next":{"headline":"Path traversal in n/a","id":"CVE-2017-5583"},"packages":[],"prev":{"headline":"Memory corruption in n/a","id":"CVE-2017-5580"},"products":["n/a"],"published":"2017-02-28","related":[{"cvss_score":9.8,"headline":"Memory corruption in TigerVNC","id":"CVE-2014-0011","kev_date_added":null,"published":"2020-01-02"},{"cvss_score":8.8,"headline":"Use after free in n/a","id":"CVE-2017-7393","kev_date_added":null,"published":"2017-04-01"},{"cvss_score":8.5,"headline":"Missing authorization in TigerVNC","id":"CVE-2026-34352","kev_date_added":null,"published":"2026-03-26"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2017-7392","kev_date_added":null,"published":"2017-04-01"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2017-7394","kev_date_added":null,"published":"2017-04-01"},{"cvss_score":7.5,"headline":"Denial of service in n/a","id":"CVE-2017-7396","kev_date_added":null,"published":"2017-04-01"}],"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 remote VNC server can execute arbitrary code on a TigerVNC client by sending a malformed RRE message with out-of-bounds subrectangles.","url":"https://insights.sbomify.com/CVE-2017-5581/"}
