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-2015-8777 in the wild and no public exploit code.\n\nAffected product: Gnu Glibc. 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-2015-8777/ (Markdown: https://insights.sbomify.com/CVE-2015-8777/index.md)","id":"CVE-2015-8777","markdown":"https://insights.sbomify.com/CVE-2015-8777/index.md","name":"CVE-2015-8777","record":{"aliases":["DEBIAN-CVE-2015-8777","GHSA-2gq8-953m-fqr3","UBUNTU-CVE-2015-8777"],"analysis":{"component_type":"operating_system","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"GNU C Library","requires_auth":"low_privilege","summary":"Local attackers can bypass pointer-guarding protections in glibc by setting a specific environment variable, undermining memory safety mechanisms.","user_interaction":"not_required","vuln_class":"security_feature_bypass"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"glibc","vendor":"gnu"}],"cvss":{"score":5.5,"severity":"medium","source":"nvd","vector":"CVSS:3.0/AV:L/AC:L/PR:L/UI:N/S:U/C:N/I:H/A:N","version":"3.0"},"cwes":[{"id":"CWE-254","name":null}],"description":"The process_envvars function in elf/rtld.c in the GNU C Library (aka glibc or libc6) before 2.23 allows local users to bypass a pointer-guarding protection mechanism via a zero value of the LD_POINTER_GUARD environment variable.","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":"Security feature bypass in n/a","id":"CVE-2015-8777","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"gnu:glibc","products":["gnu:glibc"],"type":"security_feature_bypass","year":"2015"},"n_packages":0,"n_references":15,"next":{"headline":"Integer overflow in n/a","id":"CVE-2015-8778"},"packages":[],"prev":{"headline":"Integer overflow in n/a","id":"CVE-2015-8776"},"products":["n/a"],"published":"2016-01-20","related":[{"cvss_score":9.8,"headline":"scanf %mc off-by-one heap buffer overflow","id":"CVE-2026-5450","kev_date_added":null,"published":"2026-04-20"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2023-25139","kev_date_added":null,"published":"2023-02-03"},{"cvss_score":9.8,"headline":"Other in n/a","id":"CVE-1999-0199","kev_date_added":null,"published":"2020-10-06"},{"cvss_score":9.8,"headline":"Security feature bypass in glibc","id":"CVE-2019-1010022","kev_date_added":null,"published":"2019-07-15"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2005-3590","kev_date_added":null,"published":"2019-04-10"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2017-18269","kev_date_added":null,"published":"2018-05-18"},{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2018-11236","kev_date_added":null,"published":"2018-05-18"}],"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":"2024-08-06","vendors":["n/a"]},"summary":"Local attackers can bypass pointer-guarding protections in glibc by setting a specific environment variable, undermining memory safety mechanisms.","url":"https://insights.sbomify.com/CVE-2015-8777/"}
