The specific version of ProFTPD that the system is running is reportedly affected by the following vulnerabilities:

ProFTPD contains a flaw that may result in Diffie Hellman key exchanges using 1024 bits instead of the intended 4096 bits. This may result in them being significantly less cryptographically secure. (CVE-2016-3125)
ProFTPD contains an out-of-bounds read flaw in the pr_fs_dircat() function in fsio.c that may allow a remote attacker to cause a crash or potentially disclose memory contents.
