It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2011-4029 in the wild and no public exploit code.\n\nAffected product: X.org X Server. 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-2011-4029/ (Markdown: https://insights.sbomify.com/CVE-2011-4029/index.md)","id":"CVE-2011-4029","markdown":"https://insights.sbomify.com/CVE-2011-4029/index.md","name":"CVE-2011-4029","record":{"aliases":["DEBIAN-CVE-2011-4029","GHSA-mq85-mwhp-wv55"],"analysis":{"component_type":"operating_system","fix_type":"upgrade","impacts":["data_read","denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"X.Org X Server","requires_auth":"low_privilege","summary":"Local attackers can exploit a race condition in X.Org X Server to change file permissions, read arbitrary files, or cause denial of service.","user_interaction":"not_required","vuln_class":"race_condition"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"x_server","vendor":"x.org"}],"cvss":{"score":1.9,"severity":"low","source":"nvd","vector":"AV:L/AC:M/Au:N/C:P/I:N/A:N","version":"2.0"},"cwes":[{"id":"CWE-362","name":"Concurrent Execution using Shared Resource with Improper Synchronization"}],"description":"The LockServer function in os/utils.c in X.Org xserver before 1.11.2 allows local users to change the permissions of arbitrary files to 444, read those files, and possibly cause a denial of service (removed execution permission) via a symlink attack on a temporary lock file.","ecosystems":[],"exploits":{"exploitdb":1,"first_seen":"2011-10-28","github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[{"date":"2011-10-28","kind":"exploitdb","ref":"18040","stars":null,"title":"X.Org xorg 1.4 \u003c 1.11.2 - File Permission Change"}],"tier":"poc_unverified"},"has_fix":true,"headline":"Race condition in n/a","id":"CVE-2011-4029","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"x.org:x_server","products":["x.org:x_server"],"type":"race_condition","year":"2011"},"n_packages":0,"n_references":5,"next":{"headline":"Plone anonymous access to sub-objects in CMFEditions where KwAsAttributes classes were publishable","id":"CVE-2011-4030"},"packages":[],"prev":{"headline":"Path traversal in n/a","id":"CVE-2011-4028"},"products":["n/a"],"published":"2012-07-03","related":[{"cvss_score":9,"headline":"xorg-x11-server / xwayland GLX contextTags Use-After-Free in CommonMakeCurrent()","id":"CVE-2026-56000","kev_date_added":null,"published":"2026-07-08"},{"cvss_score":8.8,"headline":"Memory corruption in n/a","id":"CVE-2017-10971","kev_date_added":null,"published":"2017-07-06"},{"cvss_score":8.5,"headline":"xorg-server / xwayland glamor font atlas Heap Buffer Overflow","id":"CVE-2026-55999","kev_date_added":null,"published":"2026-07-08"},{"cvss_score":7.8,"headline":"Memory corruption in xorg-x11-server","id":"CVE-2022-2319","kev_date_added":null,"published":"2022-09-01"},{"cvss_score":7.8,"headline":"Memory corruption in xorg-x11-server","id":"CVE-2022-2320","kev_date_added":null,"published":"2022-09-01"},{"cvss_score":7.8,"headline":"Memory corruption in xorg-x11-server","id":"CVE-2020-14360","kev_date_added":null,"published":"2021-01-20"},{"cvss_score":7.8,"headline":"Memory corruption in n/a","id":"CVE-2019-17624","kev_date_added":null,"published":"2019-10-16"}],"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)"},{"class":"attribution","licence":"GPL-2.0-or-later","name":"Exploit-DB"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":"PUBLISHED","updated":"2024-09-17","vendors":["n/a"]},"summary":"Local attackers can exploit a race condition in X.Org X Server to change file permissions, read arbitrary files, or cause denial of service.","url":"https://insights.sbomify.com/CVE-2011-4029/"}
