Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2017-7393 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-2017-7393/ (Markdown: https://insights.sbomify.com/CVE-2017-7393/index.md)","id":"CVE-2017-7393","markdown":"https://insights.sbomify.com/CVE-2017-7393/index.md","name":"CVE-2017-7393","record":{"aliases":["DEBIAN-CVE-2017-7393","GHSA-6qmp-qcvf-x3pr"],"analysis":{"component_type":"desktop_application","fix_type":"patch","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"VNC client","requires_auth":"low_privilege","summary":"An authenticated client can trigger a double free in TigerVNC, causing denial of service or potential code execution.","user_interaction":"not_required","vuln_class":"use_after_free"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"tigervnc","vendor":"tigervnc"}],"cvss":{"score":8.8,"severity":"high","source":"nvd","vector":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H","version":"3.0"},"cwes":[{"id":"CWE-415","name":"Double Free"}],"description":"In TigerVNC 1.7.1 (VNCSConnectionST.cxx VNCSConnectionST::fence), an authenticated client can cause a double free, leading to denial of service or potentially code execution.","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":"Use after free in n/a","id":"CVE-2017-7393","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"use_after_free","year":"2017"},"n_packages":0,"n_references":4,"next":{"headline":"Denial of service in n/a","id":"CVE-2017-7394"},"packages":[],"prev":{"headline":"Denial of service in n/a","id":"CVE-2017-7392"},"products":["n/a"],"published":"2017-04-01","related":[{"cvss_score":9.8,"headline":"Memory corruption in TigerVNC","id":"CVE-2014-0011","kev_date_added":null,"published":"2020-01-02"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2017-5581","kev_date_added":null,"published":"2017-02-28"},{"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":"An authenticated client can trigger a double free in TigerVNC, causing denial of service or potential code execution.","url":"https://insights.sbomify.com/CVE-2017-7393/"}
