 - add preliminary patch to fix use of uninitialized pointer / double-free in
 KDC (CVE-2008-0062,CVE-2008-0063) (#432620, #432621)
 - add backported patch to fix use-after-free in libgssapi_krb5
 (CVE-2007-5901)
 (#415321)
 - add backported patch to fix double-free in libgssapi_krb5 (CVE-2007-5971)
 (#415351)
 - add preliminary patch to fix incorrect handling of high-numbered
 descriptors
 in the RPC library (CVE-2008-0947) (#433596)
 - fix storage of delegated krb5 credentials when they've been wrapped up in
 spnego (#436460)
 - return a delegated credential handle even if the application didn't pass a
 location to store the flags which would be used to indicate that
 credentials
 were delegated (#436465)
 - add patch to fall back to TCP kpasswd servers for kdc-unreachable,
 can't-resolve-server, and response-too-big errors (#436467)
 - use the right sequence numbers when generating password-set/change
 requests
 for kpasswd servers after the first one (#436468)
 - backport from 1.6.3 to initialize a library-allocated get_init_creds_opt
 structure the same way we would one which was allocated by the calling
 application, to restore kinit's traditional behavior of doing a password
 change right when it detects an expired password (#436470)");
