TurboFTP Server 'PORT' Command Processing Stack Based Buffer Overflow Vulnerability

TurboFTP Server is prone to a stack-based buffer-overflow vulnerability because the application fails to perform adequate boundary checks on user-supplied data.

An attacker can exploit this issue to execute arbitrary code in the context of the affected server. Successful attacks will compromise the server and possibly the underlying computer. Failed attacks will likely cause denial-of-service conditions.

TurboFTP Server 1.30.823 is vulnerable; other versions may also be affected.
