protocol.

  - CVE-2012-1014
    By sending specially crafted AS-REQ (Authentication
    Service Request) to a KDC (Key Distribution Center), an
    attacker could make it free an uninitialized pointer,
    corrupting the heap. This can lead to process crash or
    even arbitrary code execution.

  This CVE only affects testing (wheezy) and unstable (sid)
  distributions.

  - CVE-2012-1015
    By sending specially crafted AS-REQ to a KDC, an
    attacker could make it dereference an uninitialized
    pointer, leading to process crash or even arbitrary code
    execution

In both cases, arbitrary code execution is believed to be difficult to
achieve, but might not be impossible."

      could impersonate a kadmind server and send a specially crafted packet to

Emmanuel Bouillon discovered that the MIT krb5 Key Distribution Center

a malformed AS-REQ message. A remote unauthenticated attacker could
use this to cause a denial of service or possibly execute arbitrary
code. This issue only affected Ubuntu 12.04 LTS. (CVE-2012-1014)

Simo Sorce discovered that the MIT krb5 Key Distribution Center (KDC)
daemon could dereference a NULL pointer when handling a malformed
TGS-REQ message. A remote authenticated attacker could use this to
cause a denial of service. (CVE-2012-1013)

It was discovered that the kadmin protocol implementation in MIT krb5
did not properly restrict access to the SET_STRING and GET_STRINGS
operations. A remote authenticated attacker could use this to expose
or modify sensitive information. This issue only affected Ubuntu 12.04
LTS. (CVE-2012-1012).
