Enhanced cTorrent -- stack-based overflow

Securityfocus reports:

cTorrent and dTorrent are prone to a remote buffer-overflow
vulnerability because the software fails to properly
bounds-check user-supplied input before copying it to an
insufficiently sized memory buffer.
Successful exploits allow remote attackers to execute
arbitrary machine code in the context of a vulnerable
application. Failed exploit attempts will likely result in
denial-of-service conditions.
