Synopsis

The remote FreeBSD host is missing one or more security-related updates.

Description

The PuTTY team reports :

New in 0.71 :

- Security fixes found by an EU-funded bug bounty programme :

- + a remotely triggerable memory overwrite in RSA key exchange, which can occur before host key verification

- + potential recycling of random numbers used in cryptography

- + on Unix, remotely triggerable buffer overflow in any kind of server-to-client forwarding

- + multiple denial-of-service attacks that can be triggered by writing to the terminal

- Other security enhancements: major rewrite of the crypto code to remove cache and timing side channels.

- User interface changes to protect against fake authentication prompts from a malicious server.
