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/OSV-2025-803/ (Markdown: https://insights.sbomify.com/OSV-2025-803/index.md)","id":"OSV-2025-803","markdown":"https://insights.sbomify.com/OSV-2025-803/index.md","name":"OSV-2025-803","record":{"aliases":[],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service"],"network_reachable":"unknown","non_default_config":false,"product_category":"iCalendar library","requires_auth":"none","summary":"A global buffer overflow in the iCalendar library allows attackers to cause a denial of service via crafted input.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"OSS-Fuzz report: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=448424495\n\n```\nCrash type: Global-buffer-overflow READ 4\nCrash state:\nicaltime_day_of_year\nexpand_bymonth_days\nexpand_year_days\n```","ecosystems":["OSS-Fuzz"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":false,"headline":"Global-buffer-overflow in icaltime_day_of_year","id":"OSV-2025-803","indexable":true,"kev":null,"kind":"advisory","links":{"ecosystem":"OSS-Fuzz","product":null,"products":[],"type":"memory_corruption","year":"2025"},"n_packages":1,"n_references":null,"packages":[{"ecosystem":"OSS-Fuzz","fixed":[],"introduced":[],"last_affected":[],"package":"libical","purl":"pkg:generic/libical","source":"OSV-2025-803"}],"products":null,"published":"2025-10-02","related":[],"sources":[{"class":"attribution","licence":"CC BY 4.0","name":"OSS-Fuzz","prefix":"OSV"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":"A global buffer overflow in the iCalendar library allows attackers to cause a denial of service via crafted input.","url":"https://insights.sbomify.com/OSV-2025-803/"}
