"The remote MiracleLinux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the
AXSA:2011-37:01 advisory.

    Kerberos V5 is a trusted-third-party network authentication system, which can improve your network's
    security by eliminating the insecure practice of cleartext passwords.
    Security issues fixed with this release:
    CVE-2010-4022
    The do_standalone function in the MIT krb5 KDC database propagation daemon (kpropd) in Kerberos 1.7, 1.8,
    and 1.9, when running in standalone mode, does not properly handle when a worker child process exits
    abnormally, which allows remote attackers to cause a denial of service (listening process termination, no
    new connections, and lack of updates in slave KVC) via unspecified vectors.
    CVE-2011-0281
    The unparse implementation in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.6.x through
    1.9, when an LDAP backend is used, allows remote attackers to cause a denial of service (file descriptor
    exhaustion and daemon hang) via a principal name that triggers use of a backslash escape sequence, as
    demonstrated by a n sequence.
    CVE-2011-0282
    The Key Distribution Center (KDC) in MIT Kerberos 5 (aka krb5) 1.6.x through 1.9, when an LDAP backend is
    used, allows remote attackers to cause a denial of service (NULL pointer dereference or buffer over-read,
    and daemon crash) via a crafted principal name.
