CVEs: CVE-2018-13405

Systems running Virtuozzo 4.7 or the OpenVZ RHEL 6 kernel can now use
Ksplice to patch against the latest Parallels Virtuozzo Containers 4.7

INSTALLING THE UPDATES

We recommend that all users of Ksplice Uptrack running Virtuozzo 4.7
or OpenVZ on RHEL 6 install these updates.

On systems that have "autoinstall = yes" in /etc/uptrack/uptrack.conf,
these updates will be installed automatically and you do not need to
take any action.

Alternatively, you can install these updates by running:

# /usr/sbin/uptrack-upgrade -y


DESCRIPTION

* CVE-2018-13405: Permissions bypass when creating file in SGID directory.

Creating an executable file in an SGID directory can result in the file
having the group ownership of the directory. This can be exploited to
elevate privileges if the file is created in a directory owned by a
privileged group.
