Virtuozzo 6 : parallels-server-bm-release / vzkernel / etc (VZA-2017-090)

high Nessus Plugin ID 103571

Synopsis

The remote Virtuozzo host is missing a security update.

Description

According to the version of the parallels-server-bm-release / vzkernel / etc packages installed, the Virtuozzo installation on the remote host is affected by the following vulnerability :

 - A flaw was found in the way the Linux kernel loaded ELF executables. Provided that an application was built as Position Independent Executable (PIE), the loader could allow part of that application's data segment to map over the memory area reserved for its stack, potentially resulting in memory corruption. An unprivileged local user with access to SUID (or otherwise privileged) PIE binary could use this flaw to escalate their privileges on the system.

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

Solution

Update the affected parallels-server-bm-release / vzkernel / etc package.
