Red Hat Security Advisory 2017-2796-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. Security Fix: A flaw was found in the way the Linux kernel loaded ELF executables. Provided that an application was built as Position Independent Executable, 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 PIE binary could use this flaw to escalate their privileges on the system.

Red Hat Security Advisory

Synopsis: Important: kernel security update
Advisory ID: RHSA-2017:2796-01
Product: Red Hat Enterprise Linux
Advisory URL: https://access.redhat.com/errata/RHSA-2017:2796
Issue date: 2017-09-26
CVE Names: CVE-2017-1000253
=====================================================================

1. Summary:

An update for kernel is now available for Red Hat Enterprise Linux 6.7
Extended Update Support.

Red Hat Product Security has rated this update as having a security impact
of Important. A Common Vulnerability Scoring System (CVSS) base score,
which gives a detailed severity rating, is available for each vulnerability
from the CVE link(s) in the References section.

2. Relevant releases/architectures:

Red Hat Enterprise Linux HPC Node EUS (v. 6.7) - noarch, x86_64
Red Hat Enterprise Linux HPC Node Optional EUS (v. 6.7) - x86_64
Red Hat Enterprise Linux Server EUS (v. 6.7) - i386, noarch, ppc64, s390x, x86_64
Red Hat Enterprise Linux Server Optional EUS (v. 6.7) - i386, ppc64, s390x, x86_64

3. Description:

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.

4. Solution:

For details on how to apply this update, which includes the changes
described in this advisory, refer to:

https://access.redhat.com/articles/11258

The system must be rebooted for this update to take effect.

5. Bugs fixed (https://bugzilla.redhat.com/):

1492212 - CVE-2017-1000253 kernel: load_elf_ binary() does not take account of the need to allocate sufficient space for the entire binary
