Published: Translated: NVD NIST

Summary

CVE-2017-2789 affects JustSystems Ichitaro Office 2016 Trial, where during the copying of file data into a buffer, the application may choose a value larger than the buffer size, leading to a heap-based buffer overflow. This overflow can allow code execution under the context of the application.

Risk Assessment

The risk to the organization involves the potential for malicious code execution, which could lead to data loss or system takeover.

Recommendation

It is recommended to update the software to the latest version to mitigate this vulnerability and to monitor systems for potential exploitation attempts.

Original NVD description (English source)

When copying filedata into a buffer, JustSystems Ichitaro Office 2016 Trial will calculate two values to determine how much data to copy from the document. If both of these values are larger than the size of the buffer, the application will choose the smaller of the two and trust it to copy data from the file. This value is larger than the buffer size, which leads to a heap-based buffer overflow. This overflow corrupts an offset in the heap used in pointer arithmetic for writing data and can lead to code execution under the context of the application.
