Category:Amazon Linux Local Security Checks
Title:Amazon Linux: Security Advisory (ALAS-2016-683)
Summary:The remote host is missing an update for the 'libssh2' package(s) announced via the ALAS-2016-683 advisory.
Description:Summary:
The remote host is missing an update for the 'libssh2' package(s) announced via the ALAS-2016-683 advisory.

Vulnerability Insight:
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.

Affected Software/OS:
'libssh2' package(s) on Amazon Linux.

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
