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
<impact type="high">
A local attacker could exploit this vulnerability to execute arbitrary
code with elevated privileges.
There is no known workaround at this time.
All MIT Kerberos 5 users should upgrade to the latest version:
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=app-crypt/mit-krb5-1.4.3-r3&quot;</code>
