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-2025-20260 in the wild and no public exploit code.\n\nAffected product: Clamav Clamav. 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-2025-20260/ (Markdown: https://insights.sbomify.com/CVE-2025-20260/index.md)","id":"CVE-2025-20260","markdown":"https://insights.sbomify.com/CVE-2025-20260/index.md","name":"CVE-2025-20260","record":{"aliases":["AZL-64208","AZL-64223","DEBIAN-CVE-2025-20260","GHSA-596c-w2jc-jmmx","MGASA-2025-0190","MINI-fhjj-4mmh-hh4p","OESA-2025-1693","OESA-2025-1694","OESA-2025-1695","OESA-2025-1696","OESA-2025-1763","UBUNTU-CVE-2025-20260"],"analysis":{"component_type":"server_software","fix_type":"patch","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":false,"product_category":"ClamAV antivirus engine","requires_auth":"none","summary":"Remote attackers can cause denial of service or potentially execute arbitrary code via crafted PDF files processed by ClamAV.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"cisco","cpe":[{"product":"clamav","vendor":"clamav"}],"cvss":{"score":9.8,"severity":"critical","source":"cna","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H","version":"3.1"},"cwes":[{"id":"CWE-122","name":"Heap-based Buffer Overflow"}],"description":"A vulnerability in the PDF scanning processes of ClamAV could allow an unauthenticated, remote attacker to cause a buffer overflow condition, cause a denial of service (DoS) condition, or execute arbitrary code on an affected device.\r\n\r\nThis vulnerability exists because memory buffers are allocated incorrectly when PDF files are processed. An attacker could exploit this vulnerability by submitting a crafted PDF file to be scanned by ClamAV on an affected device. A successful exploit could allow the attacker to trigger a buffer overflow, likely resulting in the termination of the ClamAV scanning process and a DoS condition on the affected software. Although unproven, there is also a possibility that an attacker could leverage the buffer overflow to execute arbitrary code with the privileges of the ClamAV process.","ecosystems":[],"exploits":{"exploitdb":0,"first_seen":"2025-10-27","github_poc":2,"max_poc_stars":0,"metasploit":0,"nuclei":0,"refs":[{"date":"2025-10-27T22:17:21Z","kind":"github_poc","ref":"https://github.com/Alex-Acero-Security/CVE-2025-20260-POC","stars":0,"title":null},{"date":"2025-11-13T00:24:05Z","kind":"github_poc","ref":"https://github.com/keyuraghao/CVE-2025-20260","stars":0,"title":"First public PoC for CVE-2025-20260 (CVSS 9.8) - a ClamAV PDF-scanning buffer overflow, with core-dump analysis."}],"tier":"poc_unverified"},"has_fix":true,"headline":"ClamAV PDF Scanning Buffer Overflow Vulnerability","id":"CVE-2025-20260","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"clamav:clamav","products":["clamav:clamav"],"type":"memory_corruption","year":"2025"},"n_packages":0,"n_references":1,"next":{"headline":"Cisco Integrated Management Controller Privilege Escalation Vulnerability","id":"CVE-2025-20261"},"packages":[],"prev":{"headline":"Cisco ThousandEyes Endpoint Agent for Windows Arbitrary File Write Vulnerability","id":"CVE-2025-20259"},"products":["ClamAV"],"published":"2025-06-18","related":[{"cvss_score":10,"headline":"Security feature bypass in n/a","id":"CVE-2010-0098","kev_date_added":null,"published":"2010-04-08"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2009-1372","kev_date_added":null,"published":"2009-04-23"},{"cvss_score":10,"headline":"Denial of service in n/a","id":"CVE-2008-3914","kev_date_added":null,"published":"2008-09-09"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2008-0728","kev_date_added":null,"published":"2008-02-12"},{"cvss_score":10,"headline":"Other in n/a","id":"CVE-2006-1615","kev_date_added":null,"published":"2006-04-06"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2013-7087","kev_date_added":null,"published":"2019-11-15"}],"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)"},{"class":"open","licence":"CC0","name":"PoC-in-GitHub"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"total"},"state":"PUBLISHED","updated":"2026-02-26","vendors":["Cisco"]},"summary":"Remote attackers can cause denial of service or potentially execute arbitrary code via crafted PDF files processed by ClamAV.","url":"https://insights.sbomify.com/CVE-2025-20260/"}
