Mageia Linux Local Security Checks mgasa-2016-0022

Vulnerability Insight:
An information leak flaw was found in the way the OpenSSH client roaming feature was implemented. A malicious server could potentially use this flaw to leak portions of memory (possibly including private SSH keys) of a successfully authenticated OpenSSH client (CVE-2016-0777). A buffer overflow flaw was found in the way the OpenSSH client roaming feature was implemented. A malicious server could potentially use this flaw to execute arbitrary code on a successfully authenticated OpenSSH client if that client used certain non-default configuration options (CVE-2016-0778). The issue only affects OpenSSH clients making use of the ProxyCommand feature. This update disables the roaming feature completely.

Solution:
Update the affected packages to the latest available version.
