+ <title>MIT Kerberos 5: Arbitrary remote code execution</title>

+ Multiple vulnerabilities in MIT Kerberos 5 could potentially result in
+ unauthenticated remote root code execution.

+ <background>
+ <p>
+ MIT Kerberos 5 is a suite of applications that implement the Kerberos
+ network protocol.
+ </p>
+ </background>
+ <description>
+ <p>
+ 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).
+ </p>
+ </description>
+ <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.
+ </p>
+ </impact>
+ <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 &quot;&gt;=app-crypt/mit-krb5-1.5.2-r1&quot;</code>
+ </resolution>
