MIT Kerberos 5 is a suite of applications that implement the Kerberos
|

network protocol.

The Kerberos telnet daemon fails to properly handle usernames allowing
|
|
unauthorized access to any account (CVE-2007-0956). The Kerberos
|
|
administration daemon, the KDC and possibly other applications using
|
|
the MIT Kerberos libraries are vulnerable to the following issues. The
|
|
krb5_klog_syslog function from the kadm5 library fails to properly
|
|
validate input leading to a stack overflow (CVE-2007-0957). The GSS-API
|
|
library is vulnerable to a double-free attack (CVE-2007-1216).
|
|

|
|
<impact type="high">
|
|
<p>
|
|
By exploiting the telnet vulnerability a remote attacker may obtain
|
|
access with root privileges. The remaining vulnerabilities may allow an
|
|
authenticated remote attacker to execute arbitrary code with root
|
|
privileges.

<workaround>
|
|
<p>
|
|
There is no known workaround at this time.

|
</p>
|

</workaround>
|
|
<resolution>
|
|
<p>
|
|
All MIT Kerberos 5 users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=app-crypt/mit-krb5-1.5.2-r1"</code>
