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.

Affected Software

Name Vendor Start Version End Version
Openssh Openbsd 5.7 5.7
Openssh Openbsd 5.6 5.6
