MIT Kerberos 5 is a suite of applications that implement the Kerberos
|
|
network protocol. It is designed to provide strong authentication for
|
|
client/server applications by using secret-key cryptography.

|
Unchecked calls to setuid() in krshd and v4rcp, as well as unchecked
|
|
calls to seteuid() in kftpd and in ksu, have been found in the MIT
|
|
Kerberos 5 program suite and may lead to a local root privilege
|
|
escalation.
