Red Hat Security Advisory
Synopsis: Important: kernel security and bug fix update
Advisory ID: RHSA-2018:1346-01
Product: Red Hat Enterprise Linux
Advisory URL: https://access.redhat.com/errata/RHSA-2018:1346
Issue date: 2018-05-08
CVE Names: CVE-2018-8897
=====================================================================
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):
* hw: cpu: speculative execution permission faults handling (CVE-2017-5754)
* Kernel: error in exception handling leads to DoS (CVE-2018-8897)
For more details about the security issue(s), including the impact, a CVSS
score, and other related information, refer to the CVE page(s) listed in
the References section.
Red Hat would like to thank Google Project Zero for reporting CVE-2017-5754
and Nick Peterson (Everdox Tech LLC) and Andy Lutomirski for reporting
CVE-2018-8897.
Bug Fix(es):
* The kernel build requirements have been updated to the GNU Compiler
Collection (GCC) compiler version that has the support for Retpolines. The
Retpolines mechanism is a software construct that leverages specific
knowledge of the underlying hardware to mitigate the branch target
injection, also known as Spectre variant 2 vulnerability described in
CVE-2017-5715. (BZ#1554253)
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/):
1519781 - CVE-2017-5754 hw: cpu: speculative execution permission faults handling
1567074 - CVE-2018-8897 Kernel: error in exception handling leads to DoS

Red Hat Security Advisory
Synopsis: Important: kernel security and bug fix update
Advisory ID: RHSA-2018:1351-01
Product: Red Hat Enterprise Linux
Advisory URL: https://access.redhat.com/errata/RHSA-2018:1351
Issue date: 2018-05-08
CVE Names: CVE-2018-8897
=====================================================================
1. Summary:
An update for kernel is now available for Red Hat Enterprise Linux 6.6
Advanced Update Support and Red Hat Enterprise Linux 6.6 Telco 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 Server AUS (v. 6.6) - noarch, x86_64
Red Hat Enterprise Linux Server Optional AUS (v. 6.6) - x86_64
Red Hat Enterprise Linux Server Optional TUS (v. 6.6) - x86_64
Red Hat Enterprise Linux Server TUS (v. 6.6) - noarch, x86_64
3. Description:
The kernel packages contain the Linux kernel, the core of any Linux
operating system.
Security Fix(es):
* hw: cpu: speculative execution permission faults handling (CVE-2017-5754)
* Kernel: error in exception handling leads to DoS (CVE-2018-8897)
For more details about the security issue(s), including the impact, a CVSS
score, and other related information, refer to the CVE page(s) listed in
the References section.
Red Hat would like to thank Google Project Zero for reporting CVE-2017-5754
and Nick Peterson (Everdox Tech LLC) and Andy Lutomirski for reporting
CVE-2018-8897.
Bug Fix(es):
* If an NFSv3 client mounted a subdirectory of an exported file system, a
directory entry to the mount hosting the export was incorrectly held even
after clearing the cache. Consequently, attempts to unmount the
subdirectory with the umount command failed with the EBUSY error. With this
update, the underlying source code has been fixed, and the unmount
operation now succeeds as expected in the described situation. (BZ#1538588)
* The kernel build requirements have been updated to the GNU Compiler
Collection (GCC) compiler version that has the support for Retpolines. The
Retpolines mechanism is a software construct that leverages specific
knowledge of the underlying hardware to mitigate the branch target
injection, also known as Spectre variant 2 vulnerability described in
CVE-2017-5715. (BZ#1554254)
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/):
1519781 - CVE-2017-5754 hw: cpu: speculative execution permission faults handling
1567074 - CVE-2018-8897 Kernel: error in exception handling leads to DoS
