The remote host is affected by the vulnerability described in GLSA-200409-19 (Heimdal: ftpd root escalation)
Przemyslaw Frasunek discovered several flaws in lukemftpd, which also apply to Heimdal ftpd's out-of-band signal handling code.
Additionally, a potential vulnerability that could lead to Denial of Service by the Key Distribution Center (KDC) has been fixed in this version.
Impact :
A remote attacker could be able to run arbitrary code with escalated privileges, which can result in a total compromise of the server.
Workaround :
There is no known workaround at this time.
