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-2026-33812 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 0.39.0\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-2026-33812/ (Markdown: https://insights.sbomify.com/CVE-2026-33812/index.md)","id":"CVE-2026-33812","markdown":"https://insights.sbomify.com/CVE-2026-33812/index.md","name":"CVE-2026-33812","record":{"aliases":["CLEANSTART-2026-LM41855","DEBIAN-CVE-2026-33812","GO-2026-4962","MINI-459p-hj64-qjg3","MINI-68jc-m8q8-wm7w","MINI-6w4h-w5wp-3977","MINI-77x4-ggvh-6wjq","MINI-7gx2-cpf9-849v","MINI-7v8r-6j2q-62gg","MINI-c2wh-jw7f-4qvm","MINI-cc6f-wj96-4fvr","MINI-f3f3-xm6j-p6w5","MINI-h2jv-c6fg-3896","MINI-jgq3-gg32-fr99","MINI-mf33-xhhq-ggmv","MINI-rg7h-6m73-jcj2","MINI-vm9x-69c2-crjq","UBUNTU-CVE-2026-33812"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["denial_of_service"],"network_reachable":"adjacent_or_local","non_default_config":false,"product_category":"Go image library","requires_auth":"none","summary":"Attackers can cause denial of service by triggering excessive memory allocation when the Go image library parses malicious SFNT font files.","user_interaction":"required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Go","cpe":[{"product":"image","vendor":"golang"}],"cvss":{"score":6.1,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:L/AC:L/PR:N/UI:R/S:U/C:L/I:N/A:H","version":"3.1"},"cwes":[{"id":"CWE-770","name":"Allocation of Resources Without Limits or Throttling"}],"description":"Parsing a malicious font file can cause excessive memory allocation.","ecosystems":["Go"],"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":"Excessive memory allocation when decoding malicious SFNT in golang.org/x/image","id":"CVE-2026-33812","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":1,"n_references":3,"next":{"headline":"Panic when decoding large WEBP image on 32-bit platforms in golang.org/x/image","id":"CVE-2026-33813"},"packages":[{"ecosystem":"Go","fixed":["0.39.0"],"introduced":["0"],"last_affected":[],"package":"golang.org/x/image","purl":"pkg:golang/golang.org/x/image","source":"GO-2026-4962"}],"prev":{"headline":"Crash when handling long CNAME response in net","id":"CVE-2026-33811"},"products":["golang.org/x/image/font/sfnt"],"published":"2026-04-21","related":[{"cvss_score":7.5,"headline":"Panic when decoding large WEBP image on 32-bit platforms in golang.org/x/image","id":"CVE-2026-33813","kev_date_added":null,"published":"2026-04-21"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"class":"attribution","licence":"CC BY 4.0","name":"Go Vulnerability Database","prefix":"GO"},{"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":"2026-04-21","vendors":["golang.org/x/image"]},"summary":"Attackers can cause denial of service by triggering excessive memory allocation when the Go image library parses malicious SFNT font files.","url":"https://insights.sbomify.com/CVE-2026-33812/"}
