CVE-2016-4290 is an integer overflow vulnerability affecting Hancom Office 2014. When processing a Hangul HShow Document (.hpt), the application fails to validate an integer addition, leading to an undersized buffer allocation. This allows for a heap-based buffer overflow, potentially resulting in arbitrary code execution. This vulnerability has a CVSSv3 score of 7.8 (High), indicating a significant risk. It requires user interaction (UI:R) to open a malicious document, but the attack complexity is low (AC:L), and it can lead to complete compromise of confidentiality, integrity, and availability (C:H/I:H/A:H). Currently, there is no evidence of active exploitation (KEV: No), nor are there publicly available exploit modules or proof-of-concept code (Metasploit, Nuclei, ExploitDB: None). Community discussion and media coverage for this CVE are minimal.
