null pointer dereference in krl.c?
Hi,
In ssh_krl_from_blob(), krl.c:984,
/* Record keys used to sign the KRL */
xrealloc(ca_used, nca_used + 1, sizeof(*ca_used));
ca_used[nca_used++] = key;

Thanks.

Bug in KRL signature verification
I believe there has been a bug in KRL signature verification that has been
present since the KRL feature was first introduced. It prevents signed KRLs
from being loaded by OpenSSH [0]. I believe this bug applies to all
versions of OpenSSH, although the majority of my effort has been devoted to
(and all of my code snippets come from) openssl-portable.
The bug is that an offset is incorrectly
