CVE-2015-6418: Infoleak
First published: Sun Dec 13 2015(Updated: )
The random-number generator on Cisco Small Business RV routers 4.x and SA500 security appliances 2.2.07 does not have sufficient entropy, which makes it easier for remote attackers to determine a TLS key pair via unspecified computations upon handshake key-exchange data, aka Bug ID CSCus15224.
