FKIE_CVE-2016-4294

Vulnerability from fkie_nvd - Published: 2017-01-06 21:59 - Updated: 2025-04-20 01:37
Severity ?
7.8 (High) - CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H
Summary
When opening a Hangul Hcell Document (.cell) and processing a property record within the Workbook stream, Hancom Office 2014 will attempt to allocate space for an element using a length from the file. When copying user-supplied data to this buffer, however, the application will use a different size which leads to a heap-based buffer overflow. This vulnerability can lead to code-execution under the context of the application.
