Certain Heimdal components, ftpd and rcp, are vulnerable to a local privilege escalation.
Heimdal is a free implementation of Kerberos 5.
The ftpd and rcp applications provided by Heimdal fail to check the return value of calls to seteuid().
A local attacker could exploit this vulnerability to execute arbitrary code with elevated privileges.
There is no known workaround at this time.
All Heimdal users should upgrade to the latest version:
