Description brian.broussard 2012-01-25 11:39:30 EST
Description of problem:

The key_certify function in usr.bin/ssh/key.c in OpenSSH 5.6 and 5.7, when generating legacy certificates using the -t command-line option in ssh-keygen, does not initialize the nonce field, which might allow remote attackers to obtain sensitive stack memory contents or make it easier to conduct hash collision attacks.


Expected results: 

As Fedora 15 in still in support, one would aspect a new openssh release to be placed in a Fedora 15 rpm... it is currently in Fedora 16 & 17 (as is expected). 

I am not stating this as an issue NIST is.... thus I must comply

hopefully it is in the works...
