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.

For the stable distribution (squeeze), this problem has been fixed in
version 1.8.3+dfsg-4squeeze6.

For the testing distribution (wheezy), this problem has been fixed in
version 1.10.1+dfsg-2.

For the unstable distribution (sid), this problem has been fixed in
version 1.10.1+dfsg-2.

We recommend that you upgrade your krb5 packages.";
