Vendor Solution
The following software releases have been updated to resolve this specific issue: Junos OS 12.2X50-D70 13.1X50-D30 13.2X51-D25 13.2X51-D30 13.2X52-D15 14.1X53-D10, and all subsequent releases. It is recommended to regenerate SSH keys or self signed certificates.
Vendor Workaround
Avoid generating SSH keys or self-signed SSL certificates on the affected platforms until the system has been up and running for some time, allowing additional sources of randomness to generate sufficient entropy.

EUVD |
EUVD-2015-3088 | On the QFX3500 and QFX3600 platforms, the number of bytes collected from the RANDOM_INTERRUPT entropy source when the device boots up is insufficient, possibly leading to weak or duplicate SSH keys or self-signed SSL/TLS certificates. Entropy increases after the system has been up and running for some time, but immediately after boot, the entropy is very low. This issue only affects the QFX3500 and QFX3600 switches. No other Juniper Networks products or platforms are affected by this weak entropy vulnerability. |
