"The remote MiracleLinux 4 host has packages installed that are affected by multiple vulnerabilities as referenced in the
AXSA:2012-836:04 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-2012-1013
    The check_1_6_dummy function in lib/kadm5/srv/svr_principal.c in kadmind in MIT Kerberos 5 (aka krb5)
    1.8.x, 1.9.x, and 1.10.x before 1.10.2 allows remote authenticated administrators to cause a denial of
    service (NULL pointer dereference and daemon crash) via a KRB5_KDB_DISALLOW_ALL_TIX create request that
    lacks a password.
     CVE-2012-1015
    The kdc_handle_protected_negotiation function in the Key Distribution Center (KDC) in MIT Kerberos 5 (aka
    krb5) 1.8.x, 1.9.x before 1.9.5, and 1.10.x before 1.10.3 attempts to calculate a checksum before
    verifying that the key type is appropriate for a checksum, which allows remote attackers to execute
    arbitrary code or cause a denial of service (uninitialized pointer free, heap memory corruption, and
    daemon crash) via a crafted AS-REQ request.

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.
