This can lead to potential truncation\nor overruns during the initialisation of some symmetric ciphers.\n\nImpact summary: A truncation in the IV can result in non-uniqueness,\nwhich could result in loss of confidentiality for some cipher modes.\n\nWhen calling EVP_EncryptInit_ex2(), EVP_DecryptInit_ex2() or\nEVP_CipherInit_ex2() the provided OSSL_PARAM array is processed after\nthe key and IV have been established.  Any alterations to the key length,\nvia the \"keylen\" parameter or the IV length, via the \"ivlen\" parameter,\nwithin the OSSL_PARAM array will not take effect as intended, potentially\ncausing truncation or overreading of these values.  The following ciphers\nand cipher modes are impacted: RC2, RC4, RC5, CCM, GCM and OCB.\n\nFor the CCM, GCM and OCB cipher modes, truncation of the IV can result in\nloss of confidentiality.  For example, when following NIST's SP 800-38D\nsection 8.2.1 guidance for constructing a deterministic IV for AES in\nGCM mode, truncation of the counter portion could lead to IV reuse.\n\nBoth truncations and overruns of the key and overruns of the IV will\nproduce incorrect results and could, in some cases, trigger a memory\nexception.  However, these issues are not currently assessed as security\ncritical.\n\nChanging the key and/or IV lengths is not considered to be a common operation\nand the vulnerable API was recently introduced. Furthermore it is likely that\napplication developers will have spotted this problem during testing since\ndecryption would fail unless both peers in the communication were similarly\nvulnerable. For these reasons we expect the probability of an application being\nvulnerable to this to be quite low. However if an application is vulnerable then\nthis issue is considered very serious. For these reasons we have assessed this\nissue as Moderate severity overall.\n\nThe OpenSSL SSL/TLS implementation is not affected by this issue.\n\nThe OpenSSL 3.0 and 3.1 FIPS providers are not affected by this because\nthe issue lies outside of the FIPS provider boundary.\n\nOpenSSL 3.1 and 3.0 are vulnerable to this issue."},{"lang":"es","value":"Resumen del problema: se ha identificado un error en el procesamiento de longitudes de clave y vector de inicialización (IV). Esto puede provocar posibles truncamientos o desbordamientos durante la inicialización de algunos cifrados simétricos. Resumen de impacto: un truncamiento en el IV puede dar como resultado una falta de unicidad, lo que podría resultar en la pérdida de confidencialidad para algunos modos de cifrado. Al llamar a EVP_EncryptInit_ex2(), EVP_DecryptInit_ex2() or EVP_CipherInit_ex2(), la matriz OSSL_PARAM proporcionada se procesa después de que se hayan establecido la clave y el IV. Cualquier modificación en la longitud de la clave, a través del parámetro \"keylen\" o la longitud del IV, a través del parámetro \"ivlen\", dentro de la matriz OSSL_PARAM no tendrá efecto según lo previsto, lo que podría provocar el truncamiento o la sobrelectura de estos valores. Los siguientes cifrados y modos de cifrado se ven afectados: RC2, RC4, RC5, CCM, GCM y OCB. Para los modos de cifrado CCM, GCM y OCB, el truncamiento del IV puede provocar una pérdida de confidencialidad. Por ejemplo, al seguir la guía de la sección 8.2.1 SP 800-38D del NIST para construir un IV determinista para AES en modo GCM, el truncamiento de la parte del contador podría llevar a la reutilización del IV. Tanto los truncamientos como los desbordamientos de la clave y del IV producirán resultados incorrectos y, en algunos casos, podrían desencadenar una excepción de memoria. Sin embargo, actualmente estos problemas no se consideran críticos para la seguridad. Cambiar la clave y/o las longitudes de IV no se considera una operación común y la API vulnerable se introdujo recientemente. Además, es probable que los desarrolladores de aplicaciones hayan detectado este problema durante las pruebas, ya que el descifrado fallaría a menos que ambos interlocutores en la comunicación fueran igualmente vulnerables. Por estas razones, esperamos que la probabilidad de que una aplicación sea vulnerable a esto sea bastante baja. Sin embargo, si una aplicación es vulnerable, el problema se considera muy grave. Por estos motivos, hemos evaluado este problema como de gravedad moderada en general. La implementación de OpenSSL SSL/TLS no se ve afectada por este problema. Los proveedores FIPS OpenSSL 3.0 y 3.1 no se ven afectados por esto porque el problema se encuentra fuera de los límites del proveedor FIPS. OpenSSL 3.1 y 3.0 son vulnerables a este problema."}],"metrics":{"cvssMetricV31":[{"source":"nvd@nist.gov","type":"Primary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","baseScore":7.5,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"NONE","availabilityImpact":"NONE"},"exploitabilityScore":3.9,"impactScore":3.6},{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N","baseScore":7.5,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"NONE","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"NONE","availabilityImpact":"NONE"},"exploitabilityScore":3.9,"impactScore":3.6}]},"weaknesses":[{"source":"openssl-security@openssl.org","type":"Secondary","description":[{"lang":"en","value":"CWE-684"}]},{"source":"nvd@nist.gov","type":"Primary","description":[{"lang":"en","value":"NVD-CWE-noinfo"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:openssl:openssl:*:*:*:*:*:*:*:*","versionStartIncluding":"3.0.0","versionEndExcluding":"3.0.12","matchCriteriaId":"2240B7FC-1779-4714-AA52-C4F4E2AB6FA5"},{"vulnerable":true,"criteria":"cpe:2.3:a:openssl:openssl:*:*:*:*:*:*:*:*","versionStartIncluding":"3.1.0","versionEndExcluding":"3.1.4","matchCriteriaId":"FB1AEA3A-8C1A-4A57-8932-DDCCB9DE798C"}]}]},{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:debian:debian_linux:12.0:*:*:*:*:*:*:*","matchCriteriaId":"46D69DCC-AE4D-4EA5-861C-D60951444C6C"}]}]},{"operator":"AND","nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:netapp:h300s_firmware:-:*:*:*:*:*:*:*","matchCriteriaId":"6770B6C3-732E-4E22-BF1C-2D2FD610061C"}]},{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":false,"criteria":"cpe:2.3:h:netapp:h300s:*:*:*:*:*:*:*:*","matchCriteriaId":"A4F5761B-B747-4110-9849-B6D4C14B24A6"}]}]},{"operator":"AND","nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:netapp:h410s_firmware:-:*:*:*:*:*:*:*","matchCriteriaId":"D0B4AD8A-F172-4558-AEC6-FF424BA2D912"}]},{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":false,"criteria":"cpe:2.3:h:netapp:h410s:*:*:*:*:*:*:*:*","matchCriteriaId":"D033CBC9-59FE-48D6-9D30-C4895FB957B8"}]}]},{"operator":"AND","nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:netapp:h500s_firmware:-:*:*:*:*:*:*:*","matchCriteriaId":"7FFF7106-ED78-49BA-9EC5-B889E3685D53"}]},{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":false,"criteria":"cpe:2.3:h:netapp:h500s:*:*:*:*:*:*:*:*","matchCriteriaId":"09B76C01-3DA1-461D-98F2-4858AF542D84"}]}]},{"operator":"AND","nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:netapp:h700s_firmware:-:*:*:*:*:*:*:*","matchCriteriaId":"56409CEC-5A1E-4450-AA42-641E459CC2AF"}]},{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":false,"criteria":"cpe:2.3:h:netapp:h700s:*:*:*:*:*:*:*:*","matchCriteriaId":"6D3E5A63-DA59-4582-9D38-26E9225B0BA0"}]}]},{"operator":"AND","nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:o:netapp:h410c_firmware:-:*:*:*:*:*:*:*","matchCriteriaId":"234DEFE0-5CE5-4B0A-96B8-5D227CB8ED31"}]},{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":false,"criteria":"cpe:2.3:h:netapp:h410c:-:*:*:*:*:*:*:*","matchCriteriaId":"CDDF61B7-EC5C-467C-B710-B89F502CD04F"}]}]}],"references":[{"url":"https://git.openssl.org/gitweb/?p=openssl.git;a=commitdiff;h=0df40630850fb2740e6be6890bb905d3fc623b2d","source":"openssl-security@openssl.org","tags":["Mailing
