3) Description of Vulnerability
Secunia Research has discovered a vulnerability in NJStar Word
Processor, which can be exploited by malicious people to compromise a
user's system.
The vulnerability is caused due to a boundary error within the
handling of font names read from a NJStar document file (".njx").
This can be exploited to cause a stack-based buffer overflow.
Successful exploitation allows arbitrary code execution when a
malicious ".njx" file is opened.
