Amazon Linux AMI : openssh (ALAS-2013-165)

medium Nessus Plugin ID 69724

Language:

Synopsis

The remote Amazon Linux AMI host is missing a security update.

Description

Due to the way the pam_ssh_agent_auth PAM module was built, the glibc's error() function was called rather than the intended error() function in pam_ssh_agent_auth to report errors. As these two functions expect different arguments, it was possible for an attacker to cause an application using pam_ssh_agent_auth to crash, disclose portions of its memory or, potentially, execute arbitrary code.
(CVE-2012-5536)

Solution

Run 'yum update openssh' to update your system.
