    Several vulnerabilities were discovered in krb5, the MIT implementation
    of Kerberos. The Common Vulnerabilities and Exposures project identifies
    the following problems:
    
    CVE-2015-8629
    
        It was discovered that an authenticated attacker can cause kadmind
        to read beyond the end of allocated memory by sending a string
        without a terminating zero byte. Information leakage may be possible
        for an attacker with permission to modify the database.
    
    CVE-2015-8630
    
        It was discovered that an authenticated attacker with permission to
        modify a principal entry can cause kadmind to dereference a null
        pointer by supplying a null policy value but including KADM5_POLICY
        in the mask.
    
    CVE-2015-8631
    
        It was discovered that an authenticated attacker can cause kadmind
        to leak memory by supplying a null principal name in a request which
        uses one. Repeating these requests will eventually cause kadmind to
        exhaust all available memory.
    
    For the oldstable distribution (wheezy), these problems have been fixed
    in version 1.10.1+dfsg-5+deb7u7. The oldstable distribution (wheezy) is
    not affected by CVE-2015-8630.
    
    For the stable distribution (jessie), these problems have been fixed in
    version 1.12.1+dfsg-19+deb8u2.
    
    We recommend that you upgrade your krb5 packages.
