Title:	Mageia: Security Advisory (MGASA-2016-0082)
Summary:	The remote host is missing an update for the 'libssh' package(s) announced via the MGASA-2016-0082 advisory.
Description:	Summary: The remote host is missing an update for the 'libssh' package(s) announced via the MGASA-2016-0082 advisory. Vulnerability Insight: Updated libssh packages fix security vulnerability: libssh versions 0.1 and above have a bits/bytes confusion bug and generate an abnormally short ephemeral secret for the diffie-hellman-group1 and diffie-hellman-group14 key exchange methods. The resulting secret is 128 bits long, instead of the recommended sizes of 1024 and 2048 bits respectively. Both client and server are vulnerable, pre-authentication. This vulnerability could be exploited by an eavesdropper with enough resources to decrypt or intercept SSH sessions (CVE-2016-0739). Affected Software/OS: 'libssh' package(s) on Mageia 5. Solution: Please install the updated package(s). CVSS Score: 4.3 CVSS Vector: AV:N/AC:M/Au:N/C:P/I:N/A:N
