430399 - vfychain -pp crashes

Status: RESOLVED FIXED

Attachment: zip file of DER cert files to reproduce this bug

I have a chain of test certs. 3 certs (EE, intermediate, root CA) in 3 files.
If I use the command 
 vfychain -d empty -pvv BridgeUser1cert.der NavyBridgecert.der -t ArmyRoot.der
to validate the chain, it crashes.  

The cause is the same as the cause of bug 428038, namely a crash in 
cert_pkixDestroyValOutParam when the ValOutParams block has not been 
initialized to zeros.  We do want to fix that in the library, but the 
patch is not ready.  In the mean time, I have a fix for vfychain.c that
I will attach.  It simply initializes the valOutParams.

This patch initializes the structures we pass to CERT_PKIXVerifyCert.

In the above cited command, "empty" is the name of a directory containing
an empty cert DB, the result of 
   certutil -d empty -N
