It can only be exploited from the same machine or local network, with no action from the victim.\nExploitation: It is not confirmed as exploited in the wild, but public exploit code for CVE-2026-103658 exists.\n\nAffected product: GNU Aspell. 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-2026-103658/ (Markdown: https://insights.sbomify.com/CVE-2026-103658/index.md)","id":"CVE-2026-103658","markdown":"https://insights.sbomify.com/CVE-2026-103658/index.md","name":"CVE-2026-103658","record":{"aliases":["AZL-108060","BELL-CVE-2026-103658","DEBIAN-CVE-2026-103658","ECHO-25af-2f91-edc1","GHSA-p35p-2mw5-fj5j","UBUNTU-CVE-2026-103658","openSUSE-SU-2026:12126-1"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service","code_execution"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"GNU Aspell library","requires_auth":"none","summary":"A heap-based buffer overflow in GNU Aspell allows attackers to cause denial of service or execute code by tricking users into loading a malicious dictionary file.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Anthropic","cpe":[],"cvss":{"score":5.9,"severity":"medium","source":"cna","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:N/S:U/C:L/I:L/A:L","version":"3.1"},"cwes":[{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"GNU Aspell 0.60.8.2 (first vulnerable version is not known) contains a heap-based buffer overflow write (CWE-122) in its read-only dictionary loader. String::reserve() in common/string.hpp computes its capacity check with a signed int ((int)s + 1), so a requested size of 0x7FFFFFFF wraps negative and the backing buffer is never grown. ReadOnlyDict::load() in modules/speller/default/readonly_ws.cpp passes the unvalidated 32-bit size fields from a .rws dictionary header into this path, so a crafted .rws file with a valid endian marker (12345678) and an oversized length field (e.g. lang_name_size = 0x7FFFFFFF) causes attacker-controlled data to be written out of bounds past an undersized heap allocation. An attacker who induces a victim to load a malicious dictionary — for example via aspell dump master \u003cfile\u003e — can corrupt heap memory, resulting in denial of service and potentially code execution. Fixed in b830b6e and will be fixed in release 0.60.8.3.","ecosystems":["openSUSE:Tumbleweed"],"exploits":{"exploitdb":0,"first_seen":null,"github_poc":0,"max_poc_stars":null,"metasploit":0,"nuclei":0,"refs":[],"tier":"weaponised"},"has_fix":true,"headline":"Memory corruption in Aspell","id":"CVE-2026-103658","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"memory_corruption","year":"2026"},"n_packages":1,"n_references":1,"next":{"headline":"MISP: Object Distribution ACL Bypass via Event Flattening Exposes Organisation-Only Attributes","id":"CVE-2026-103659"},"packages":[{"ecosystem":"openSUSE:Tumbleweed","fixed":["0.60.8.2-3.1"],"introduced":["0"],"last_affected":[],"package":"aspell","purl":"pkg:rpm/opensuse/aspell\u0026distro=openSUSE%20Tumbleweed","source":"openSUSE-SU-2026:12126-1"}],"prev":{"headline":"this is rejected","id":"CVE-2026-103656"},"products":["Aspell"],"published":"2026-10-12","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"SUSE","prefix":"openSUSE"},{"class":"attribution","licence":"CWE Terms of Use","name":"CWE (MITRE)"},{"class":"attribution","licence":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"no","exploitation":"poc","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-10-14","vendors":["GNU"]},"summary":"A heap-based buffer overflow in GNU Aspell allows attackers to cause denial of service or execute code by tricking users into loading a malicious dictionary file.","url":"https://insights.sbomify.com/CVE-2026-103658/"}
