The remote Gentoo host is missing one or more security-related
The remote host is affected by the vulnerability described in GLSA-200704-02
(MIT Kerberos 5: Arbitrary remote code execution)
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).
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
There is no known workaround at this time.
