3) Description of Vulnerability
Secunia Research has discovered a vulnerability in TUGZip, which can
be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to a boundary error when handling an
ARJ archive containing a file with an overly long filename. This can
be exploited to cause a stack-based buffer overflow.
Successful exploitation allows arbitrary code execution when a
malicious ARJ file is opened.
