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-2023-6129 in the wild and no public exploit code.\n\nAffected product: Openssl Openssl. 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-2023-6129/ (Markdown: https://insights.sbomify.com/CVE-2023-6129/index.md)","id":"CVE-2023-6129","markdown":"https://insights.sbomify.com/CVE-2023-6129/index.md","name":"CVE-2023-6129","record":{"aliases":["ALPINE-CVE-2023-6129","AZL-35044","AZL-35085","AZL-42697","AZL-42754","AZL-47643","AZL-78582","CLEANSTART-2026-MW33481","DEBIAN-CVE-2023-6129","GHSA-rj8q-prqp-jwfg","JLSEC-2026-245","UBUNTU-CVE-2023-6129"],"analysis":{"component_type":"library","fix_type":"patch","impacts":["denial_of_service","code_execution"],"network_reachable":"yes","non_default_config":true,"product_category":"OpenSSL cryptographic library","requires_auth":"none","summary":"A bug in OpenSSL's POLY1305 implementation on PowerPC corrupts vector registers, potentially causing crashes or code execution in TLS servers.","user_interaction":"not_required","vuln_class":"memory_corruption"},"analysis_generated_by":"qwen3.8-flash-next","assigner":"openssl","cpe":[{"product":"openssl","vendor":"openssl"}],"cvss":{"score":6.5,"severity":"medium","source":"cisa-adp","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:L/A:H","version":"3.1"},"cwes":[{"id":"CWE-787","name":"Out-of-bounds Write"},{"id":"CWE-440","name":"Expected Behavior Violation"}],"description":"Issue summary: The POLY1305 MAC (message authentication code) implementation\ncontains a bug that might corrupt the internal state of applications running\non PowerPC CPU based platforms if the CPU provides vector instructions.\n\nImpact summary: If an attacker can influence whether the POLY1305 MAC\nalgorithm is used, the application state might be corrupted with various\napplication dependent consequences.\n\nThe POLY1305 MAC (message authentication code) implementation in OpenSSL for\nPowerPC CPUs restores the contents of vector registers in a different order\nthan they are saved. Thus the contents of some of these vector registers\nare corrupted when returning to the caller. The vulnerable code is used only\non newer PowerPC processors supporting the PowerISA 2.07 instructions.\n\nThe consequences of this kind of internal application state corruption can\nbe various - from no consequences, if the calling application does not\ndepend on the contents of non-volatile XMM registers at all, to the worst\nconsequences, where the attacker could get complete control of the application\nprocess. However unless the compiler uses the vector registers for storing\npointers, the most likely consequence, if any, would be an incorrect result\nof some application dependent calculations or a crash leading to a denial of\nservice.\n\nThe POLY1305 MAC algorithm is most frequently used as part of the\nCHACHA20-POLY1305 AEAD (authenticated encryption with associated data)\nalgorithm. The most common usage of this AEAD cipher is with TLS protocol\nversions 1.2 and 1.3. If this cipher is enabled on the server a malicious\nclient can influence whether this AEAD cipher is used. This implies that\nTLS server applications using OpenSSL can be potentially impacted. However\nwe are currently not aware of any concrete application that would be affected\nby this issue therefore we consider this a Low severity security issue.","ecosystems":[],"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":"POLY1305 MAC implementation corrupts vector registers on PowerPC","id":"CVE-2023-6129","indexable":true,"kev":null,"kind":"cve","links":{"ecosystem":null,"product":"openssl:openssl","products":["openssl:openssl"],"type":"memory_corruption","year":"2023"},"n_packages":0,"n_references":4,"next":{"headline":"Path Traversal: '\\..\\filename' in salesagility/suitecrm","id":"CVE-2023-6130"},"packages":[],"prev":{"headline":"Cross-site Scripting (XSS) - Reflected in salesagility/suitecrm","id":"CVE-2023-6128"},"products":["OpenSSL"],"published":"2024-01-09","related":[{"cvss_score":10,"headline":"Null dereference in n/a","id":"CVE-2009-3245","kev_date_added":null,"published":"2010-03-05"},{"cvss_score":10,"headline":"Memory corruption in n/a","id":"CVE-2006-3738","kev_date_added":null,"published":"2006-09-28"},{"cvss_score":9.8,"headline":"Untrusted Sender DN Used as Format String in CMP Response Validation","id":"CVE-2026-63073","kev_date_added":null,"published":"2026-08-25"},{"cvss_score":9.8,"headline":"Use after free in n/a","id":"CVE-2016-6309","kev_date_added":null,"published":"2016-09-26"},{"cvss_score":9.8,"headline":"Integer overflow in n/a","id":"CVE-2016-0799","kev_date_added":null,"published":"2016-03-03"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2016-2842","kev_date_added":null,"published":"2016-03-03"},{"cvss_score":9.8,"headline":"Memory corruption in n/a","id":"CVE-2003-0545","kev_date_added":null,"published":"2003-10-01"}],"sources":[{"class":"attribution","licence":"CVE Terms of Use (MITRE)","name":"CVE List","prefix":"CVE"},{"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":"2026-10-14","vendors":["OpenSSL"]},"summary":"A bug in OpenSSL's POLY1305 implementation on PowerPC corrupts vector registers, potentially causing crashes or code execution in TLS servers.","url":"https://insights.sbomify.com/CVE-2023-6129/"}
