CVE-2015-3006: Juniper Junos

Medium severity, CVSS 6.5. EPSS: 0.8% chance of exploitation in the next 30 days.

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.

Affected products

• Juniper Junos: version 12.2x50 only; version 13.1x50 only; version 13.2x51 only; version 13.2x52 only; version 14.1x53 only
