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-2020-1968 in the wild and no public exploit code.\n\nAffected product: Canonical Ubuntu Linux. 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-2020-1968/ (Markdown: https://insights.sbomify.com/CVE-2020-1968/index.md)","id":"CVE-2020-1968","markdown":"https://insights.sbomify.com/CVE-2020-1968/index.md","name":"CVE-2020-1968","record":{"aliases":["DEBIAN-CVE-2020-1968","DLA-2378-1","GHSA-mh8f-5gw2-5wgh","SUSE-SU-2020:14491-1","SUSE-SU-2020:14511-1","UBUNTU-CVE-2020-1968"],"analysis":{"component_type":"library","fix_type":"upgrade","impacts":["data_read"],"network_reachable":"yes","non_default_config":true,"product_category":"OpenSSL TLS library","requires_auth":"none","summary":"Attackers can eavesdrop on encrypted TLS communications by exploiting DH secret reuse in OpenSSL, requiring DH ciphersuites.","user_interaction":"not_required","vuln_class":"weak_cryptography"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"openssl","cpe":[{"product":"ubuntu_linux","vendor":"canonical"},{"product":"debian_linux","vendor":"debian"},{"product":"m10-1_firmware","vendor":"fujitsu"},{"product":"m10-4_firmware","vendor":"fujitsu"},{"product":"m10-4s_firmware","vendor":"fujitsu"},{"product":"m12-1_firmware","vendor":"fujitsu"},{"product":"m12-2_firmware","vendor":"fujitsu"},{"product":"m12-2s_firmware","vendor":"fujitsu"},{"product":"openssl","vendor":"openssl"},{"product":"ethernet_switch_es1-24_firmware","vendor":"oracle"},{"product":"ethernet_switch_es2-64_firmware","vendor":"oracle"},{"product":"ethernet_switch_es2-72_firmware","vendor":"oracle"},{"product":"ethernet_switch_tor-72_firmware","vendor":"oracle"},{"product":"jd_edwards_world_security","vendor":"oracle"},{"product":"peoplesoft_enterprise_peopletools","vendor":"oracle"}],"cvss":{"score":3.7,"severity":"low","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:L/I:N/A:N","version":"3.1"},"cwes":[{"id":"CWE-203","name":"Observable Discrepancy"}],"description":"The Raccoon attack exploits a flaw in the TLS specification which can lead to an attacker being able to compute the pre-master secret in connections which have used a Diffie-Hellman (DH) based ciphersuite. In such a case this would result in the attacker being able to eavesdrop on all encrypted communications sent over that TLS connection. The attack can only be exploited if an implementation re-uses a DH secret across multiple TLS connections. Note that this issue only impacts DH ciphersuites and not ECDH ciphersuites. This issue affects OpenSSL 1.0.2 which is out of support and no longer receiving public updates. OpenSSL 1.1.1 is not vulnerable to this issue.
