3. Description:

The libssh2 packages provide a library that implements the SSHv2 protocol.

A type confusion issue was found in the way libssh2 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-2016-0787)

Red Hat would like to thank Aris Adamantiadis for reporting this issue.

All libssh2 users are advised to upgrade to these updated packages, which
contain a backported patch to correct this issue. After installing these
updated packages, all running applications using libssh2 must be restarted
for this update to take effect.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.
