EulerOS 2.0 SP1 : openssh (EulerOS-SA-2017-1055)

This script is Copyright (C) 2017 Tenable Network Security, Inc.


Synopsis :

The remote EulerOS host is missing multiple security updates.

Description :

According to the versions of the openssh packages installed, the
EulerOS installation on the remote host is affected by the following
vulnerabilities :

- Untrusted search path vulnerability in ssh-agent.c in
ssh-agent in OpenSSH before 7.4 allows remote attackers
to execute arbitrary local PKCS#11 modules by
leveraging control over a forwarded
agent-socket.(CVE-2016-10009)

- authfile.c in sshd in OpenSSH before 7.4 does not
properly consider the effects of realloc on buffer
contents, which might allow local users to obtain
sensitive private-key information by leveraging access
to a privilege-separated child process.(CVE-2016-10011)

Note that Tenable Network Security has extracted the preceding
description block directly from the EulerOS security advisory. Tenable
has attempted to automatically clean and format it as much as possible
without introducing additional issues.
