Summary

CVE-2017-2790 affects JustSystems Ichitaro Office, where processing a record type of 0x3c from an Excel (.xls) file leads to a buffer overflow due to incorrect size calculation. Trusting the size to be greater than zero results in a heap-based buffer overflow, potentially allowing code execution in the application's context.

Risk Assessment

Recommendation

It is recommended to update JustSystems Ichitaro Office to the latest version to mitigate this vulnerability and to monitor systems for unauthorized activities.

Original NVD description (English source)

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.
