Description

A remote overflow exists in linux-ftpd-ssl. The SSL code fails to validate input to the vsprintf() function resulting in a stack-based buffer overflow. With a specially crafted request which generates more than 2048 bytes of response from the server, a remote attacker can cause arbitrary code execution resulting in a loss of integrity.
