tag_insight = "Several vulnerabilities have been found in the MIT reference implementation
of Kerberos V5, a system for authenticating users and services on a network.
The Common Vulnerabilities and Exposures project identified the following
problems:

The Apple Product Security team discovered that the SPNEGO GSS-API mechanism
suffers of a missing bounds check when reading a network input buffer which
results in an invalid read crashing the application or possibly leaking
information (CVE-2009-0844).

Under certain conditions the SPNEGO GSS-API mechanism references a null pointer
which crashes the application using the library (CVE-2009-0845).

An incorrect length check inside the ASN.1 decoder of the MIT krb5
implementation allows an unauthenticated remote attacker to crash of the kinit
or KDC program (CVE-2009-0847).

Under certain conditions the the ASN.1 decoder of the MIT krb5 implementation
frees an uninitialized pointer which could lead to denial of service and
possibly arbitrary code execution (CVE-2009-0846).


For the oldstable distribution (etch), this problem has been fixed in
version 1.4.4-7etch7.

For the stable distribution (lenny), this problem has been fixed in
version 1.6.dfsg.4~beta1-5lenny1.

For the testing distribution (squeeze), this problem will be fixed soon.

For the unstable distribution (sid), this problem has been fixed in
version 1.6.dfsg.4~beta1-13.


We recommend that you upgrade your krb5 packages.";
