A specially crafted document can cause the document parser to explicitly trust a length from a particular record type and use it to write a 16-bit null relative to a buffer allocated on the stack. Due to a lack of bounds-checking on this value, this can allow an attacker to write to memory outside of the buffer and controllably corrupt memory. This can allow an attacker to earn code execution under the context of the application. An attacker can entice the victim to open a document to trigger this vulnerability."}, {"lang": "es", "value": "Se presenta una vulnerabilidad de desbordamiento de b\u00fafer en la regi\u00f3n heap de la memoria explotable en la funcionalidad de an\u00e1lisis de documentos de PlanMaker de la aplicaci\u00f3n PlanMaker de SoftMaker Office 2021. Un documento especialmente dise\u00f1ado puede causar que el analizador de documentos conf\u00ede expl\u00edcitamente en una longitud de un tipo de registro en particular y lo use para escribir un null de 16 bits en relaci\u00f3n con un b\u00fafer asignado en la pila. Debido a una falta de comprobaci\u00f3n de l\u00edmites en este valor, esto puede permitir a un atacante escribir en la memoria fuera del b\u00fafer y corromper la memoria de manera controlable. Esto puede permitir a un atacante ganarse la ejecuci\u00f3n de c\u00f3digo en el contexto de la aplicaci\u00f3n. Un atacante puede atraer a la v\u00edctima para que abra un documento para activar esta vulnerabilidad"}], "lastModified": "2024-11-21T05:01:32.627", "configurations": [{"nodes": [{"negate": false, "cpeMatch": [{"criteria": "cpe:2.3:a:softmaker:planmaker_2021:1014:*:*:*:*:*:*:*", "vulnerable": true, "matchCriteriaId": "80D7705E-C127-4043-BC09-31346F8AD532"}], "operator": "OR"}]}], "sourceIdentifier": "talos-cna@cisco.com"}
