Buffer Overflow vulnerability in Proftpd commit 4017eff8 allows a remote attacker to execute arbitrary code and can cause a Denial of Service (DoS) on the FTP service by sending a maliciously crafted message to the ProFTPD service port.
The product copies an input buffer to an output buffer without verifying that the size of the input buffer is less than the size of the output buffer, leading to a buffer overflow.
