Discussion

ProFTPD SReplace Remote Buffer Overflow Vulnerability

ProFTPD is prone to a remote buffer-overflow vulnerability. This issue is due to an off-by-one error, allowing attackers to corrupt memory.

Exploiting this issue allows remote attackers to execute arbitrary machine code in the context of the server application, facilitating the compromise of affected computers.

ProFTPD versions prior to 1.3.0a are vulnerable to this issue.

Update: This BID was recently updated to state that 'CommandBufferSize' was affected by a denial-of-service issue, but according to the vendor, that directive is not vulnerable.
