Description John Dennis 2013-12-18 22:05:04 UTC 
rlm_krb5 will corrupt memory or seg fault due to improperly passed pointer to memcpy.

rlm_krb5 will also seg fault due a bug in the krb5 function krb5_copy_context(), this problem and it's solution is described in Bug #1044735.

A discussion concerning the problems with rlm_krb5 can be found here:

Attached is a patch which brings all the rlm_krb5 files up to date with the current version of these files in the upstream FreeRADIUS git repo (branch v3.0.x), this will become the basis for the next FreeRADIUS 3.x release.
