|
|
This module exploits a stack buffer overflow in HT-MP3Player 1.0.
|
|
Arbitrary code execution could occur when parsing a specially crafted
|
|
.HT3 file.
|
|
|
|
NOTE: The player installation does not register the file type to be
|
|
handled. Therefore, a user must take extra steps to load this file.
