Test ID:1.3.6.1.4.1.25623.1.0.812001
Category:Red Hat Local Security Checks
Title:RedHat Update for kernel RHSA-2017:2795-01
Summary:The remote host is missing an update for the 'kernel'; package(s) announced via the referenced advisory.
Description:Summary:
The remote host is missing an update for the 'kernel'
package(s) announced via the referenced advisory.

Vulnerability Insight:
The kernel packages contain the Linux
kernel, the core of any Linux operating system.

Security Fix(es):

* 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. (CVE-2017-1000253, Important)

Red Hat would like to thank Qualys Research Labs for reporting this issue.

Affected Software/OS:
kernel on Red Hat Enterprise Linux Desktop (v. 6),
Red Hat Enterprise Linux Server (v. 6),
Red Hat Enterprise Linux Workstation (v. 6)

Solution:
Please Install the Updated Packages.

CVSS Score:
