All supported architectures
Several bugs exist in the Heimdal ftp daemon which could allow a remote
attacker to gain root privileges.
Heimdal is an implementation of Kerberos 5.
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
A remote attacker could be able to run arbitrary code with escalated
privileges, which can result in a total compromise of the server.
There is no known workaround at this time.
All Heimdal users should upgrade to the latest version:
