A use-after-free flaw was found in the way ProFTPD, an enhanced FTP server, performed retrieval of the response pool for the old command (when ProFTPD was in the midst of the data transfer, when new command arrived) used by the Response API. A remote attacker could provide a specially-crafted request (resulting in a need the server to handle an exceptional condition), leading to memory corruption and potentially arbitrary code execution, with the privileges of the user running the proftpd server.
