Description:
Tan Chew Keong has reported a vulnerability in Lhaca, which can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to a boundary error when processing .LZH archives. This can be exploited to cause a stack-based buffer overflow via a specially-crafted .LZH file with an "Extended Header Size" value greater than 255 bytes.
Successful exploitation allows execution of arbitrary code.

Solution:
