[arch-dev-public] [signoff] krb5-1.9.1-5

[Stéphane Gaudreault]

This update apply an upstream patch that fix the following KDC denial of 
service vulnerabilities [1] :

CVE-2011-1527: In releases krb5-1.9 and later, the KDC can crash due
to a null pointer dereference if configured to use the LDAP back end.
A trigger condition is publicly known but not known to be widely
circulated.

CVE-2011-1528: In releases krb5-1.8 and later, the KDC can crash due
to an assertion failure.  No exploit is known to exist, but there is
public evidence that the unidentified trigger condition occurs in the
field.

CVE-2011-1529: In releases krb5-1.8 and later, the KDC can crash due
to a null pointer dereference.  No exploit is known to exist.

Please test and signoff.

I am not sure I will have internet access at the hotel in the next days, so 
feel free to move this to [core] once it gets the required signoffs.

Cheers,

Stéphane
