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-2026-33809 in the wild and no public exploit code.\n\nAffected packages and fixed versions:\n- golang.org/x/image (Go): affected all versions; fixed in 0.38.0\n- golang.org/x/image (Go): affected all versions; fixed in 0.38.0\n- golang.org/x/image (Go): affected all versions; fixed in 0.38.0\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-2026-33809/ (Markdown: https://insights.sbomify.com/CVE-2026-33809/index.md)","id":"CVE-2026-33809","markdown":"https://insights.sbomify.com/CVE-2026-33809/index.md","name":"CVE-2026-33809","record":{"aliases":["CLEANSTART-2026-GN98127","CLEANSTART-2026-WK70772","DEBIAN-CVE-2026-33809","GHSA-44p7-9xx4-hf2g","GO-2026-4815","MINI-cwrc-x497-qhwj","MINI-jfpm-8m77-8fgx","MINI-qmqv-mvc7-825c","MINI-vcgc-6g36-635c","MINI-wgqj-c84v-g3f7","MINI-x2fm-fr59-m8xc","UBUNTU-CVE-2026-33809","openSUSE-SU-2026:10628-1"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"yes","non_default_config":false,"product_category":"Go image library","requires_auth":"none","summary":"Attackers can cause denial of service by providing a malicious TIFF file that triggers excessive memory allocation in the Go image library.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Go","cpe":[{"product":"tiff","vendor":"golang"}],"cvss":{"score":5.3,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-434","name":"Unrestricted Upload of File with Dangerous Type"}],"description":"A maliciously crafted TIFF file can cause image decoding to attempt to allocate up 4GiB of memory, causing either excessive resource consumption or an out-of-memory error.","ecosystems":["Go","openSUSE:Tumbleweed"],"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":"OOM from malicious IFD offset in golang.org/x/image/tiff","id":"CVE-2026-33809","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":4,"n_references":3,"next":{"headline":"Case-sensitive excludedSubtrees name constraints cause Auth Bypass in crypto/x509","id":"CVE-2026-33810"},"packages":[{"ecosystem":"Go","fixed":["0.38.0"],"introduced":["0"],"last_affected":[],"package":"golang.org/x/image","purl":null,"source":"GHSA-44p7-9xx4-hf2g"},{"ecosystem":"Go","fixed":["0.38.0"],"introduced":["0"],"last_affected":[],"package":"golang.org/x/image","purl":"pkg:golang/golang.org/x/image","source":"GHSA-44p7-9xx4-hf2g"},{"ecosystem":"Go","fixed":["0.38.0"],"introduced":["0"],"last_affected":[],"package":"golang.org/x/image","purl":"pkg:golang/golang.org/x/image","source":"GO-2026-4815"},{"ecosystem":"openSUSE:Tumbleweed","fixed":["0.37.3-1.1"],"introduced":["0"],"last_affected":[],"package":"pocketbase","purl":"pkg:rpm/opensuse/pocketbase\u0026distro=openSUSE%20Tumbleweed","source":"openSUSE-SU-2026:10628-1"}],"prev":{"headline":"@fastify/express has a middleware authentication bypass via URL normalization gaps (duplicate slashes and semicolons)","id":"CVE-2026-33808"},"products":["golang.org/x/image/tiff"],"published":"2026-03-25","related":[{"cvss_score":7.5,"headline":"Panic decoding image with out-of-bounds strip offset in x/image/tiff in golang.org/x/image","id":"CVE-2026-46604","kev_date_added":null,"published":"2026-06-26"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"GitHub Advisory Database","prefix":"GHSA"},{"class":"attribution","licence":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"class":"attribution","licence":"CC BY 4.0","name":"SUSE","prefix":"openSUSE"},{"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":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-04-06","vendors":["golang.org/x/image"]},"summary":"Attackers can cause denial of service by providing a malicious TIFF file that triggers excessive memory allocation in the Go image library.","url":"https://insights.sbomify.com/CVE-2026-33809/"}
