HIGHJustSystems Ichitaro - Heap-Based Buffer Overflow via Excel Workbook Stream Record Type 0x3c
Title source: llmDescription
When processing a record type of 0x3c from a Workbook stream from an Excel file (.xls), JustSystems Ichitaro Office trusts that the size is greater than zero, subtracts one from the length, and uses this result as the size for a memcpy. This results in a heap-based buffer overflow and can lead to code execution under the context of the application.
