Hancom

Hancom develops a suite of office productivity applications and word processors that are prominently deployed in East Asian markets, with a vulnerability footprint spanning multiple product generations including Hancom Office and Hangul Word Processor. The vendor's disclosures cluster around memory-safety and bounds-checking weaknesses—improper buffer restrictions, out-of-bounds writes, use-after-free conditions, integer overflows, and stack-based buffer overflows—that reflect the native-code implementation and parsing demands of document processing software. Vulnerabilities affecting this vendor lean toward serious outcomes, with a meaningful share reaching critical severity. Defenders should prioritize patches for this vendor's products, particularly in environments where older office suite versions remain in active use, since document-processing flaws can be weaponized through seemingly benign user interaction. Current exploitation activity, severity distribution, and exposure counts are shown alongside this summary.
