Descriptions

A specially crafted document can cause the document parser to copy data from a particular record type into a static-sized buffer within an object that is smaller than the size used for the copy, which will cause a heap-based buffer overflow. An attacker can entice the victim to open a document to trigger this vulnerability. This affects SoftMaker Software GmbH SoftMaker Office PlanMaker 2021 (Revision 1014).

Un documento especialmente diseñado puede causar que el analizador de documentos copie datos de un tipo de registro en particular en un búfer de tamaño estático dentro de un objeto que es más pequeño que el tamaño usado para la copia, lo que causará un desbordamiento del búfer en la región heap de la memoria. Un atacante puede atraer a la víctima para que abra un documento para desencadenar esta vulnerabilidad. Esto afecta a SoftMaker Software GmbH SoftMaker Office PlanMaker 2021 (Revisión 1014)
