Test ID:1.3.6.1.4.1.25623.1.1.10.2016.0392
Category:Mageia Linux Local Security Checks
Title:Mageia: Security Advisory (MGASA-2016-0392)
Summary:The remote host is missing an update for the 'libssh2' package(s) announced via the MGASA-2016-0392 advisory.
Description:Summary:
The remote host is missing an update for the 'libssh2' package(s) announced via the MGASA-2016-0392 advisory.

Vulnerability Insight:
Andreas Schneider reported that libssh2 passes the number of bytes to a
function that expects number of bits during the SSHv2 handshake when
libssh2 is to get a suitable value for 'group order' in the Diffie-Hellman
negotiation. This weakens significantly the handshake security,
potentially allowing an eavesdropper with enough resources to decrypt or
intercept SSH sessions (CVE-2016-0787).

Affected Software/OS:
'libssh2' 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
