Any signed-in user can exploit it over the network, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-56002 in the wild and no public exploit code.\n\nAffected product: X.Org libXfont2. 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-2026-56002/ (Markdown: https://insights.sbomify.com/CVE-2026-56002/index.md)","id":"CVE-2026-56002","markdown":"https://insights.sbomify.com/CVE-2026-56002/index.md","name":"CVE-2026-56002","record":{"aliases":["AZL-92087","BELL-CVE-2026-56002","DEBIAN-CVE-2026-56002","ECHO-4e4f-e6d6-0780","GHSA-r49w-hq6h-2w8q","UBUNTU-CVE-2026-56002"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"X.Org font library","requires_auth":"low_privilege","summary":"Authenticated X clients can execute arbitrary code in the X server via a heap buffer overflow in libXfont2's PCF font parser.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"suse","cpe":[{"product":"libxfont","vendor":"x"}],"cvss":{"score":8.5,"severity":"high","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:C/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"A heap bufferflow in pcfReadFont() due to missing glyph bounds checking in libXfont2 before 2.0.8  allows attackers authenticated as X client to execute code within the X server.","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":"libXfont2 PCF Font Parsing Heap Buffer Overflow","id":"CVE-2026-56002","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"libXfont2 computeProps Property Buffer Heap Buffer Overflow","id":"CVE-2026-56003"},"packages":[],"prev":{"headline":"libXfont2 BitmapScaleBitmaps Integer Overflow Heap Buffer Overflow","id":"CVE-2026-56001"},"products":["libXfont2"],"published":"2026-07-08","related":[{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2007-5199","kev_date_added":null,"published":"2017-08-18"},{"cvss_score":9.3,"headline":"Memory corruption in n/a","id":"CVE-2013-6462","kev_date_added":null,"published":"2014-01-09"},{"cvss_score":8.5,"headline":"libXfont2 BitmapScaleBitmaps Integer Overflow Heap Buffer Overflow","id":"CVE-2026-56001","kev_date_added":null,"published":"2026-07-08"},{"cvss_score":8.5,"headline":"libXfont2 computeProps Property Buffer Heap Buffer Overflow","id":"CVE-2026-56003","kev_date_added":null,"published":"2026-07-08"},{"cvss_score":8.5,"headline":"Memory corruption in n/a","id":"CVE-2015-1802","kev_date_added":null,"published":"2015-03-20"},{"cvss_score":8.5,"headline":"Integer overflow in n/a","id":"CVE-2015-1804","kev_date_added":null,"published":"2015-03-20"}],"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":"no","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-07-09","vendors":["X.Org"]},"summary":"Authenticated X clients can execute arbitrary code in the X server via a heap buffer overflow in libXfont2's PCF font parser.","url":"https://insights.sbomify.com/CVE-2026-56002/"}
