DProxy DNS_Decode_Reverse_Name Buffer-Overflow Vulnerability

Dproxy is prone to a remote buffer-overflow vulnerability because it fails to properly check boundaries on user-supplied data before copying it to an insufficiently sized buffer.

Exploiting this issue could lead to denial-of-service conditions and to the execution of arbitrary machine code with superuser privileges. A successful attack could result in the complete compromise of affected computers or routers/devices.

Version 1.c is vulnerable; other versions may also be affected.
