Total Commander Buffer Overflow (Exploit)
------------------------------------------------------------------------
SUMMARY
<http://www.ghisler.com/> Total Commander is a file manager for Windows,
a program like Windows Explorer to copy, move or delete files. However,
Total Commander can do much more than Explorer, e.g. pack and unpack
files, access ftp servers, compare files by content, etc!
Total Commander is vulnerable to a buffer overflow when opening malformed
ace archive files.
DETAILS
Vulnerable Systems:
* Total Commander versions 6.x
