Synopsis :

The remote Mandriva Linux host is missing one or more security
updates.

Description :

Updated libssh2 packages fix security vulnerability :

Mariusz Ziulek reported that libssh2, a SSH2 client-side library, was
reading and using the SSH_MSG_KEXINIT packet without doing sufficient
range checks when negotiating a new SSH session with a remote server.
A malicious attacker could man in the middle a real server and cause a
client using the libssh2 library to crash (denial of service) or
otherwise read and use unintended memory areas in this process
(CVE-2015-1782).

Update :

Packages were misssing for Mandriva Business Server 1 with the
MDVSA-2015:148 advisory which are now being provided.
