Description SMASH SMASH 2023-12-19 13:51:12 UTC

In ssh-agent in OpenSSH before 9.6, certain destination constraints can be incompletely applied. When destination constraints are specified during addition of PKCS#11-hosted private keys, these constraints are only applied to the first key, even if a PKCS#11 token returns multiple keys.

also ALP is affected

submit to:
SUSE:ALP:Source:Standard:1.0 openssh

Comment 5 Marcus Meissner 2024-05-21 09:08:00 UTC

as the feature was only added in recent openssh versions, the security problem does not apply to earlier versions than 9.3p1
