CVSS v3.1
Official Description
Stack-based buffer overflow in NJStar Chinese and Japanese Word Processor 4.x and 5.x before 5.10 allows user-assisted attackers to execute arbitrary code via font names in NJStar (.njx) documents.
Technical Analysis
CVE-2006-0807 can be exploited remotely over the network without requiring physical or adjacent access, significantly expanding the attack surface for threat actors.
Exploitation requires some privileges, which limits the exposure to scenarios where an attacker has already gained initial access.
From a weakness classification perspective (CWE-119): Buffer overflow vulnerabilities can lead to arbitrary code execution or denial of service by corrupting adjacent memory.
