Description

The libssh2 packages provide a library that implements the SSHv2 protocol.A type confusion issue was found in the way libssh2 generated ephemeralsecrets for the diffie-hellman-group1 and diffie-hellman-group14 keyexchange methods. This would cause an SSHv2 Diffie-Hellman handshake to usesignificantly 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, whichcontain a backported patch to correct this issue. After installing theseupdated packages, all running applications using libssh2 must be restartedfor this update to take effect.
