F5 Networks BIG-IP : Hosts may generate weak RSA keys under low entropy conditions (SOL13607)

high Nessus Plugin ID 78137

Language:

Synopsis

The remote device is missing a vendor-supplied security patch.

Description

A recent study, linked in the Supplemental Information section, has revealed that when a system generates new RSA keys under low-entropy conditions, such as during the first system boot, the resulting keys may not be cryptographically strong.

Solution

Upgrade to one of the non-vulnerable versions listed in the F5 Solution SOL13607.
