EulerOS 2.0 SP1 : kernel (EulerOS-SA-2016-1018)

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 kernel packages installed, the
EulerOS installation on the remote host is affected by the following
vulnerabilities :

- A flaw was found in the way the Linux kernel's file
system implementation handled rename operations in
which the source was inside and the destination was
outside of a bind mount. A privileged user inside a
container could use this flaw to escape the bind mount
and, potentially, escalate their privileges on the
system.(CVE-2015-2925)

- A race condition flaw was found in the way the Linux
kernel's IPC subsystem initialized certain fields in an
IPC object structure that were later used for
permission checking before inserting the object into a
globally visible list. A local, unprivileged user could
potentially use this flaw to elevate their privileges
on the system.(CVE-2015-7613)

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.
