<title>MIT Kerberos 5: Arbitrary remote code execution</title>
Multiple vulnerabilities in MIT Kerberos 5 could potentially result in
remote code execution with root privileges by unauthenticated users.

MIT Kerberos 5 is a suite of applications that implement the Kerberos
network protocol.
kadmind is affected by multiple vulnerabilities in the RPC library
shipped with MIT Kerberos 5. It fails to properly handle zero-length
RPC credentials (CVE-2007-2442) and the RPC library can write past the
end of the stack buffer (CVE-2007-2443). Furthermore kadmind fails to
do proper bounds checking (CVE-2007-2798).
<impact type="high">
A remote unauthenticated attacker could exploit these vulnerabilities
to execute arbitrary code with root 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-krb5-1.5.2-r3&quot;</code>
