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-2026-42500 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 0.41.0\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-2026-42500/ (Markdown: https://insights.sbomify.com/CVE-2026-42500/index.md)","id":"CVE-2026-42500","markdown":"https://insights.sbomify.com/CVE-2026-42500/index.md","name":"CVE-2026-42500","record":{"aliases":["CLEANSTART-2026-FA97173","DEBIAN-CVE-2026-42500","GHSA-m6fh-wvw4-4629","GO-2026-5031","MINI-3w5m-3576-rwgw","MINI-3xjc-h726-h3r4","MINI-4gfm-rmc3-7cv5","MINI-4m45-px7h-hmf7","MINI-5787-ggpc-hvwx","MINI-67gc-2q6f-xf6j","MINI-73c4-72rw-g92x","MINI-84c2-pgm8-rpqc","MINI-9jcr-4g89-xrhr","MINI-f9f3-cjgm-x7wq","MINI-ffhg-jgh6-44r2","MINI-fggj-8ff5-ff54","MINI-gf24-w6w7-68xh","MINI-h3m9-jj4j-rwx2","MINI-h7jm-w95v-6vpx","MINI-hjmj-p3p5-rhjw","MINI-jfwg-694g-2w23","MINI-m7xm-jw9w-gxvm","MINI-mr8c-7qjg-8hmp","MINI-pjhw-c2pc-jqxq","MINI-qj9q-f6fr-mx7q","MINI-r39f-43jh-2p8g","MINI-r9fr-8v9m-hv2j","MINI-vrc5-qr64-fg5w","MINI-wf8r-936m-j4wg","MINI-wm4j-x357-j5w7","MINI-wq2f-667j-gw26","MINI-xfw8-g3xh-5w52","MINI-xgjx-mrvf-h69m","UBUNTU-CVE-2026-42500"],"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":"An attacker can cause a denial of service by providing a malformed BMP file with an out-of-range palette index, crashing the application using the Go image library.","user_interaction":"not_required","vuln_class":"denial_of_service"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"Go","cpe":[],"cvss":{"score":5.3,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:L","version":"3.1"},"cwes":[],"description":"Decoding a paletted BMP file with an out-of-range palette index results in a panic when accessing pixels in the invalid image.","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":"Panic when reading out of bound palette index in golang.org/x/image/bmp","id":"CVE-2026-42500","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":"Go","product":null,"products":[],"type":"denial_of_service","year":"2026"},"n_packages":1,"n_references":4,"next":{"headline":"Malicious module proxy can bypass checksum database in cmd/go","id":"CVE-2026-42501"},"packages":[{"ecosystem":"Go","fixed":["0.41.0"],"introduced":["0"],"last_affected":[],"package":"golang.org/x/image","purl":"pkg:golang/golang.org/x/image","source":"GO-2026-5031"}],"prev":{"headline":"Quadratic string concatenation in consumePhrase in net/mail","id":"CVE-2026-42499"},"products":["golang.org/x/image/bmp"],"published":"2026-05-29","related":[],"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":"FIRST CVSS licence","name":"CVSS (FIRST)"}],"ssvc":{"automatable":"yes","exploitation":"none","technical_impact":"partial"},"state":"PUBLISHED","updated":"2026-05-29","vendors":["golang.org/x/image"]},"summary":"An attacker can cause a denial of service by providing a malformed BMP file with an out-of-range palette index, crashing the application using the Go image library.","url":"https://insights.sbomify.com/CVE-2026-42500/"}
