Description: Ryan Smith has reported a vulnerability in WinRAR, which can be exploited by malicious people to compromise a user's system.
The vulnerability is caused due to boundary errors in lzh.fmt within the processing of LHA archives. This can be exploited to cause a stack-based buffer overflow when a specially crafted file with an overly long filename is opened.
Successful exploitation allows execution of arbitrary code with the user's privileges.
