An attacker can supply a crafted CMS message with an\noversized IV, causing a stack-based out-of-bounds write before any\nauthentication or tag verification occurs.\n\nApplications and services that parse untrusted CMS or PKCS#7 content using\nAEAD ciphers (e.g., S/MIME (Auth)EnvelopedData with AES-GCM) are vulnerable.\nBecause the overflow occurs prior to authentication, no valid key material\nis required to trigger it. While exploitability to remote code execution\ndepends on platform and toolchain mitigations, the stack-based write\nprimitive represents a severe risk.\n\nThe FIPS modules in 3.6, 3.5, 3.4, 3.3 and 3.0 are not affected by this\nissue, as the CMS implementation is outside the OpenSSL FIPS module\nboundary.\n\nOpenSSL 3.6, 3.5, 3.4, 3.3 and 3.0 are vulnerable to this issue.\n\nOpenSSL 1.1.1 and 1.0.2 are not affected by this issue."},{"lang":"es","value":"Resumen del problema: Analizar un mensaje CMS AuthEnvelopedData con parámetros AEAD creados maliciosamente puede desencadenar un desbordamiento de búfer de pila.\n\nResumen del impacto: Un desbordamiento de búfer de pila puede provocar un fallo, causando Denegación de Servicio, o potencialmente ejecución remota de código.\n\nAl analizar estructuras CMS AuthEnvelopedData que utilizan cifrados AEAD como AES-GCM, el IV (Vector de Inicialización) codificado en los parámetros ASN.1 se copia en un búfer de pila de tamaño fijo sin verificar que su longitud se ajuste al destino. Un atacante puede proporcionar un mensaje CMS manipulado con un IV de tamaño excesivo, causando una escritura fuera de límites basada en pila antes de que ocurra cualquier autenticación o verificación de etiqueta.\n\nLas aplicaciones y servicios que analizan contenido CMS o PKCS#7 no confiable utilizando cifrados AEAD (por ejemplo, S/MIME AuthEnvelopedData con AES-GCM) son vulnerables. Debido a que el desbordamiento ocurre antes de la autenticación, no se requiere material de clave válido para desencadenarlo. Si bien la explotabilidad para la ejecución remota de código depende de las mitigaciones de la plataforma y la cadena de herramientas, la primitiva de escritura basada en pila representa un riesgo grave.\n\nLos módulos FIPS en 3.6, 3.5, 3.4, 3.3 y 3.0 no se ven afectados por este problema, ya que la implementación de CMS está fuera del límite del módulo FIPS de OpenSSL.\n\nOpenSSL 3.6, 3.5, 3.4, 3.3 y 3.0 son vulnerables a este problema.\n\nOpenSSL 1.1.1 y 1.0.2 no se ven afectados por este problema."}],"metrics":{"cvssMetricV31":[{"source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","type":"Secondary","cvssData":{"version":"3.1","vectorString":"CVSS:3.1/AV:N/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H","baseScore":8.8,"baseSeverity":"HIGH","attackVector":"NETWORK","attackComplexity":"LOW","privilegesRequired":"NONE","userInteraction":"REQUIRED","scope":"UNCHANGED","confidentialityImpact":"HIGH","integrityImpact":"HIGH","availabilityImpact":"HIGH"},"exploitabilityScore":2.8,"impactScore":5.9}]},"weaknesses":[{"source":"openssl-security@openssl.org","type":"Secondary","description":[{"lang":"en","value":"CWE-787"}]}],"configurations":[{"nodes":[{"operator":"OR","negate":false,"cpeMatch":[{"vulnerable":true,"criteria":"cpe:2.3:a:openssl:openssl:*:*:*:*:*:*:*:*","versionStartIncluding":"3.0.0","versionEndExcluding":"3.0.19","matchCriteriaId":"C76C5F55-5243-4461-82F5-2FEBFF4D59FA"},{"vulnerable":true,"criteria":"cpe:2.3:a:openssl:openssl:*:*:*:*:*:*:*:*","versionStartIncluding":"3.1.0","versionEndExcluding":"3.3.6","matchCriteriaId":"791BA794-23EF-4671-B96B-3A7E3BF52490"},{"vulnerable":true,"criteria":"cpe:2.3:a:openssl:openssl:*:*:*:*:*:*:*:*","versionStartIncluding":"3.4.0","versionEndExcluding":"3.4.4","matchCriteriaId":"B9D3DCAE-317D-4DFB-93F0-7A235A229619"},{"vulnerable":true,"criteria":"cpe:2.3:a:openssl:openssl:*:*:*:*:*:*:*:*","versionStartIncluding":"3.5.0","versionEndExcluding":"3.5.5","matchCriteriaId":"1CAC7CBE-EC03-4089-938A-0CEEB2E09B62"},{"vulnerable":true,"criteria":"cpe:2.3:a:openssl:openssl:*:*:*:*:*:*:*:*","versionStartIncluding":"3.6.0","versionEndExcluding":"3.6.1","matchCriteriaId":"68352537-5E99-4F4D-B78A-BCF0353A70A5"}]}]}],"references":[{"url":"https://github.com/openssl/openssl/commit/2c8f0e5fa9b6ee5508a0349e4572ddb74db5a703","source":"openssl-security@openssl.org","tags":["Patch"]},{"url":"https://github.com/openssl/openssl/commit/5f26d4202f5b89664c5c3f3c62086276026ba9a9","source":"openssl-security@openssl.org","tags":["Patch"]},{"url":"https://github.com/openssl/openssl/commit/6ced0fe6b10faa560e410e3ee8d6c82f06c65ea3","source":"openssl-security@openssl.org","tags":["Patch"]},{"url":"https://github.com/openssl/openssl/commit/ce39170276daec87f55c39dad1f629b56344429e","source":"openssl-security@openssl.org","tags":["Patch"]},{"url":"https://github.com/openssl/openssl/commit/d0071a0799f20cc8101730145349ed4487c268dc","source":"openssl-security@openssl.org","tags":["Patch"]},{"url":"https://openssl-library.org/news/secadv/20260127.txt","source":"openssl-security@openssl.org","tags":["Vendor Advisory"]},{"url":"http://www.openwall.com/lists/oss-security/2026/01/27/10","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Mailing List"]},{"url":"http://www.openwall.com/lists/oss-security/2026/02/25/6","source":"af854a3a-2127-422b-91ae-364da2661108","tags":["Mailing List"]},{"url":"https://github.com/guiimoraes/CVE-2025-15467","source":"134c704f-9b21-4f2e-91b3-4a467353bcc0","tags":["Exploit","Third Party Advisory"]}]}}]}
