\nRed Hat Security Advisory<\/p>\n

Synopsis: Important: kernel security and bug fix update
\nAdvisory ID: RHSA-2018:2925-01
\nProduct: Red Hat Enterprise Linux
\nAdvisory URL: https:\/\/access.redhat.com\/errata\/RHSA-2018:2925
\nIssue date: 2018-10-16
\nCVE Names: CVE-2018-5391 CVE-2018-10675 CVE-2018-14634
\n=====================================================================<\/p>\n

1. Summary:<\/p>\n

An update for kernel is now available for Red Hat Enterprise Linux 6.7
\nExtended Update Support.<\/p>\n

Red Hat Product Security has rated this update as having a security impact
\nof Important. A Common Vulnerability Scoring System (CVSS) base score,
\nwhich gives a detailed severity rating, is available for each vulnerability
\nfrom the CVE link(s) in the References section.<\/p>\n

2. Relevant releases\/architectures:<\/p>\n

Red Hat Enterprise Linux HPC Node EUS (v. 6.7) – noarch, x86_64
\nRed Hat Enterprise Linux HPC Node Optional EUS (v. 6.7) – x86_64
\nRed Hat Enterprise Linux Server EUS (v. 6.7) – i386, noarch, ppc64, s390x, x86_64
\nRed Hat Enterprise Linux Server Optional EUS (v. 6.7) – i386, ppc64, s390x, x86_64<\/p>\n

3. Description:<\/p>\n

The kernel packages contain the Linux kernel, the core of any Linux
\noperating system.<\/p>\n

Security Fix(es):<\/p>\n

* A flaw named FragmentSmack was found in the way the Linux kernel handled
\nreassembly of fragmented IPv4 and IPv6 packets. A remote attacker could use
\nthis flaw to trigger time and calculation expensive fragment reassembly
\nalgorithm by sending specially crafted packets which could lead to a CPU
\nsaturation and hence a denial of service on the system. (CVE-2018-5391)<\/p>\n

* kernel: mm: use-after-free in do_get_mempolicy function allows local DoS
\nor other unspecified impact (CVE-2018-10675)<\/p>\n

* kernel: Integer overflow in Linux’s create_elf_tables function
\n(CVE-2018-14634)<\/p>\n

For more details about the security issue(s), including the impact, a CVSS
\nscore, and other related information, refer to the CVE page(s) listed in
\nthe References section.<\/p>\n

Red Hat would like to thank Juha-Matti Tilli (Aalto University – Department
\nof Communications and Networking and Nokia Bell Labs) for reporting
\nCVE-2018-5391 and Qualys Research Labs for reporting CVE-2018-14634.<\/p>\n

Bug Fix(es):<\/p>\n

* Previously, the kernel source code lacked support to report the
\nSpeculative Store Bypass Disable (SSBD) vulnerability status on IBM Power
\nSystems. As a consequence, the
\n\/sys\/devices\/system\/cpu\/vulnerabilities\/spec_store_bypass file incorrectly
\nreported “Not affected”. This fix updates the kernel source code to
\nproperly report the SSBD status either as “Vulnerable” or “Mitigation:
\nKernel entry\/exit barrier (TYPE)”, where TYPE is one of “eieio”, “hwsync”,
\n“fallback”, or “unknown”. (BZ#1615873)<\/p>\n

* After updating the system to prevent the L1 Terminal Fault (L1TF)
\nvulnerability, only one thread was detected on systems that offer
\nprocessing of two threads on a single processor core. With this update, the
\n“__max_smt_threads()” function has been fixed. As a result, both threads
\nare now detected correctly in the described situation. (BZ#1625335)<\/p>\n

* Previously, a kernel panic occurred when the kernel tried to make an out
\nof bound access to the array that describes the L1 Terminal Fault (L1TF)
\nmitigation state on systems without Extended Page Tables (EPT) support.
\nThis update extends the array of mitigation states to cover all the states,
\nwhich effectively prevents out of bound array access. Also, this update
\nenables rejecting invalid, irrelevant values, that might be erroneously
\nprovided by the userspace. As a result, the kernel no longer panics in the
\ndescribed scenario. (BZ#1629634)<\/p>\n

4. Solution:<\/p>\n

For details on how to apply this update, which includes the changes
\ndescribed in this advisory, refer to:<\/p>\n

https:\/\/access.redhat.com\/articles\/11258<\/p>\n

The system must be rebooted for this update to take effect.<\/p>\n

5. Bugs fixed (https:\/\/bugzilla.redhat.com\/):<\/p>\n

1575065 – CVE-2018-10675 kernel: mm: use-after-free in do_get_mempolicy function allows local DoS or other unspecified impact
\n1609664 – CVE-2018-5391 kernel: IP fragments with random offsets allow a remote denial of service (FragmentSmack)
\n1624498 – CVE-2018-14634 kernel: Integer overflow in Linux’s create_elf_tables function<\/p>\n
