Jzip v1.3 (.zip) Unicode buffer overflow 0day PoC
Date: 6/4/2010
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
Greetz to: Corelan Security Team
http://www.corelan.be:8800/index.php/security/corelan-team-members/
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
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 :)
