The remote Ubuntu 16.04 LTS host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-3056-1 advisory.

    Ben Hawkes discovered an integer overflow in the Linux netfilter implementation. On systems running 32 bit     kernels, a local unprivileged attacker could use this to cause a denial of service (system crash) or     possibly execute arbitrary code with administrative privileges. (CVE-2016-3135)

    It was discovered that the keyring implementation in the Linux kernel did not ensure a data structure was     initialized before referencing it after an error condition occurred. A local attacker could use this to     cause a denial of service (system crash). (CVE-2016-4470)

    Sasha Levin discovered that a use-after-free existed in the percpu allocator in the Linux kernel. A local     attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code     with administrative privileges. (CVE-2016-4794)

    Kangjie Lu discovered an information leak in the netlink implementation of the Linux kernel. A local     attacker could use this to obtain sensitive information from kernel memory. (CVE-2016-5243)

An update for kernel is now available for Red Hat Enterprise Linux 7.1 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.

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

Security Fix(es) :

* A flaw was found in the Linux kernel's keyring handling code, where in key_reject_and_link() an uninitialised variable would eventually lead to arbitrary free address which could allow attacker to use a use-after-free style attack. (CVE-2016-4470, Important)

* A flaw was found in the way certain interfaces of the Linux kernel's Infiniband subsystem used write() as bi-directional ioctl() replacement, which could lead to insufficient memory security checks when being invoked using the splice() system call. A local unprivileged user on a system with either Infiniband hardware present or RDMA Userspace Connection Manager Access module explicitly loaded, could use this flaw to escalate their privileges on the system.
(CVE-2016-4565, Important)

* A flaw was found in the implementation of the Linux kernel's handling of networking challenge ack where an attacker is able to determine the shared counter which could be used to determine sequence numbers for TCP stream injection. (CVE-2016-5696, Important)

Red Hat would like to thank Jann Horn for reporting CVE-2016-4565 and Yue Cao (Cyber Security Group of the CS department of University of California in Riverside) for reporting CVE-2016-5696. The CVE-2016-4470 issue was discovered by David Howells (Red Hat Inc.).

An update for kernel is now available for Red Hat Enterprise Linux 6.5 Advanced 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.

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

Security Fix(es) :

* A flaw was found in the Linux kernel's keyring handling code, where in key_reject_and_link() an uninitialized variable would eventually lead to arbitrary free address which could allow attacker to use a use-after-free style attack. (CVE-2016-4470, Important)

This issue was discovered by David Howells (Red Hat Inc.).

Bug Fix(es) :

* Previously, the BUG_ON() signal appeared in the fs_clear_inode() function where the nfs_have_writebacks() function reported a positive value for nfs_inode->npages. As a consequence, a kernel panic occurred. This update performs a serialization by holding the inode i_lock over the check of PagePrivate and locking the request, which fixes this bug. (BZ#1365161)

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2016:2128 advisory.

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

    Security Fix(es):

    * A flaw was found in the Linux kernel's keyring handling code: the key_reject_and_link() function could     be forced to free an arbitrary memory block. An attacker could use this flaw to trigger a use-after-free     condition on the system, potentially allowing for privilege escalation. (CVE-2016-4470, Important)

    * A race condition was found in the way the Linux kernel's memory subsystem handled the copy-on-write     (COW) breakage of private read-only memory mappings. An unprivileged, local user could use this flaw to     gain write access to otherwise read-only memory mappings and thus increase their privileges on the system.
    (CVE-2016-5195, Important)

    Red Hat would like to thank Phil Oester for reporting CVE-2016-5195. The CVE-2016-4470 issue was     discovered by David Howells (Red Hat).

    Enhancement(s):

    * This update fixes a tape write problem by fixing the use of the sas_is_tlr_enabled API in the mpt3sas     driver. The driver now checks whether Transport Layer Recovery (TLR) is enabled before enabling the     MPI2_SCSIIO_CONTROL_TLR_ON flag. (BZ#1372352)
