It can only be exploited from the same machine or local network, and only if a user opens a file or follows a link.\nExploitation: There is no known exploitation of CVE-2026-75818 in the wild and no public exploit code.\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-2026-75818/ (Markdown: https://insights.sbomify.com/CVE-2026-75818/index.md)","id":"CVE-2026-75818","markdown":"https://insights.sbomify.com/CVE-2026-75818/index.md","name":"CVE-2026-75818","record":{"aliases":["AZL-105969","BELL-CVE-2026-75818","DEBIAN-CVE-2026-75818","ECHO-704a-feda-9882","GHSA-93mw-x5wh-jf8f","UBUNTU-CVE-2026-75818"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"GNU Aspell spell checker","requires_auth":"none","summary":"A heap buffer overflow in GNU Aspell's prezip utility allows attackers to crash the application by tricking users into processing malicious compressed files.","user_interaction":"required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"CERT-PL","cpe":[],"cvss":{"score":1.8,"severity":"low","source":"cna","vector":"CVSS:4.0/AV:L/AC:H/AT:N/PR:N/UI:A/VC:N/VI:N/VA:L/SC:L/SI:L/SA:N","version":"4.0"},"cwes":[{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"GNU Aspell prezip-bin contains a heap-based buffer overflow vulnerability in the decompressor in prog/prezip.c.

An attacker who convinces a user to process a malicious compressed file with prezip-bin can trigger memory corruption, leading to a processs crash.\n\nThis issue was fixed in commit 15b188437f9e0192d4ac4472ad66a4e2f62a782f which will be released in version 0.60.8.3.","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":"Heap Buffer Overflow in GNU Aspell's prezip utility","id":"CVE-2026-75818","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":"Out-of-bounds Read in GNU Aspell","id":"CVE-2026-75819"},"packages":[],"prev":{"headline":"Frontend Admin by DynamiApps \u003c= 3.29.12 - Unauthenticated Account Takeover via '_acf_objects' Object Identifier","id":"CVE-2026-75816"},"products":["Aspell"],"published":"2026-10-06","related":[],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"partial"},"state":"PUBLISHED","updated":"2026-10-06","vendors":["GNU"]},"summary":"A heap buffer overflow in GNU Aspell's prezip utility allows attackers to crash the application by tricking users into processing malicious compressed files.","url":"https://insights.sbomify.com/CVE-2026-75818/"}
