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-2009-2409 in the wild and no public exploit code.\n\nAffected product: Gnu Gnutls. 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-2009-2409/ (Markdown: https://insights.sbomify.com/CVE-2009-2409/index.md)","id":"CVE-2009-2409","markdown":"https://insights.sbomify.com/CVE-2009-2409/index.md","name":"CVE-2009-2409","record":{"aliases":["DEBIAN-CVE-2009-2409","DSA-1888-1","GHSA-c2f9-w3c5-x385"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["security_bypass"],"network_reachable":"yes","non_default_config":false,"product_category":"SSL/TLS cryptographic library","requires_auth":"none","summary":"Remote attackers can spoof X.509 certificates by exploiting MD2 hash collisions in cryptographic libraries, bypassing certificate validation.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"redhat","cpe":[{"product":"gnutls","vendor":"gnu"},{"product":"network_security_services","vendor":"mozilla"},{"product":"openssl","vendor":"openssl"}],"cvss":{"score":5.1,"severity":"medium","source":"nvd","vector":"AV:N/AC:H/Au:N/C:P/I:P/A:P","version":"2.0"},"cwes":[{"id":"CWE-295","name":"Improper Certificate Validation"}],"description":"The Network Security Services (NSS) library before 3.12.3, as used in Firefox; GnuTLS before 2.6.4 and 2.7.4; OpenSSL 0.9.8 through 0.9.8k; and other products support MD2 with X.509 certificates, which might allow remote attackers to spoof certificates by using MD2 design flaws to generate a hash collision in less than brute-force time.
