kinda like "shooting fish in a barrel"...
The WU-FTP software package had the same problem on Sun, SGI, and a number of other unix systems. The problem was the software program did not check its input correctly, the famous stack overflow problem. The problem is that the software runs as the administrator, and when compromised the crack runs as administrator. This problem exists on Linux, Solaris, IRIX, and Windows.
Even so, I brace for the Wounded Linies to scream foul, accusing B2K of having read their poor fallen comrade's post before creating his own entry. Denial is cruel; heartlessly cruel.
