An attacker can exploit it over the internet without logging in, with no action from the victim.\nExploitation: There is no known exploitation of CVE-2026-24883 in the wild and no public exploit code.\n\nAffected product: GnuPG. 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-2026-24883/ (Markdown: https://insights.sbomify.com/CVE-2026-24883/index.md)","id":"CVE-2026-24883","markdown":"https://insights.sbomify.com/CVE-2026-24883/index.md","name":"CVE-2026-24883","record":{"aliases":["ECHO-273b-fd6d-3afe","GHSA-7246-cvp4-g68w","JLSEC-2026-566"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"GnuPG encryption library","requires_auth":"none","summary":"A long signature packet length triggers a null pointer dereference in GnuPG, causing an application crash and denial of service.","user_interaction":"not_required","vuln_class":"null_dereference"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"mitre","cpe":[{"product":"gnupg","vendor":"gnupg"},{"product":"gpg4win","vendor":"gpg4win"}],"cvss":{"score":3.7,"severity":"low","source":"cna","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[{"id":"CWE-476","name":"NULL Pointer Dereference"}],"description":"In GnuPG before 2.5.17, a long signature packet length causes parse_signature to return success with sig-\u003edata[] set to a NULL value, leading to a denial of service (application crash).","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":"Null dereference in GnuPG","id":"CVE-2026-24883","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":null,"products":[],"type":"null_dereference","year":"2026"},"n_packages":0,"n_references":2,"next":{"headline":"Compressing Vulnerable to Arbitrary File Write via Symlink Extraction","id":"CVE-2026-24884"},"packages":[],"prev":{"headline":"Memory corruption in GnuPG","id":"CVE-2026-24882"},"products":["GnuPG"],"published":"2026-01-27","related":[{"cvss_score":9.8,"headline":"Integer overflow in libksba","id":"CVE-2022-3515","kev_date_added":null,"published":"2023-01-12"},{"cvss_score":9.3,"headline":"Memory corruption in n/a","id":"CVE-2008-1530","kev_date_added":null,"published":"2008-03-27"},{"cvss_score":8.4,"headline":"Memory corruption in GnuPG","id":"CVE-2026-24882","kev_date_added":null,"published":"2026-01-27"},{"cvss_score":8.1,"headline":"Memory corruption in GnuPG","id":"CVE-2026-24881","kev_date_added":null,"published":"2026-01-27"},{"cvss_score":7.8,"headline":"Memory corruption in GnuPG","id":"CVE-2025-68973","kev_date_added":null,"published":"2025-12-28"},{"cvss_score":7.8,"headline":"Memory corruption in n/a","id":"CVE-2020-25125","kev_date_added":null,"published":"2020-09-03"},{"cvss_score":6.8,"headline":"Memory corruption in n/a","id":"CVE-2006-6169","kev_date_added":null,"published":"2006-11-29"}],"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":"partial"},"state":"PUBLISHED","updated":"2026-01-28","vendors":["GnuPG"]},"summary":"A long signature packet length triggers a null pointer dereference in GnuPG, causing an application crash and denial of service.","url":"https://insights.sbomify.com/CVE-2026-24883/"}
