libssh is a library which implements the SSH protocol. It can be used to implement client and server applications.
Security Fix(es):
- A type confusion issue was found in the way libssh generated ephemeral secrets for the diffie-hellman-group1 and diffie-hellman-group14 key exchange methods. This would cause an SSHv2 Diffie-Hellman handshake to use significantly less secure random parameters. (CVE-2016-0739)
Red Hat would like to thank Aris Adamantiadis for reporting this issue.
