| tls-ticketbleed:
|   VULNERABLE:
|   Ticketbleed is a serious issue in products manufactured by F5, a popular
vendor of TLS load-balancers. The issue allows for stealing information from
the load balancer
|     State: VULNERABLE (Exploitable)
|     Risk factor: High
|       Ticketbleed is vulnerability in the implementation of the TLS
SessionTicket extension found in some F5 products. It allows the leakage
("bleeding") of up to 31 bytes of data from unin itialized memory. This is
caused by the TLS stack padding a Session ID, passed from the client, with
data to make it 32-bits long.
