The remote Redhat Enterprise Linux 5 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2017:0323 advisory.

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

    Security Fix(es):

    * A use-after-free flaw was found in the way the Linux kernel's Datagram Congestion Control Protocol     (DCCP) implementation freed SKB (socket buffer) resources for a DCCP_PKT_REQUEST packet when the     IPV6_RECVPKTINFO option is set on the socket. A local, unprivileged user could use this flaw to alter the     kernel memory, allowing them to escalate their privileges on the system. (CVE-2017-6074, Important)

    * It was found that the Linux kernel's Datagram Congestion Control Protocol (DCCP) implementation used the     IPv4-only inet_sk_rebuild_header() function for both IPv4 and IPv6 DCCP connections, which could result in     memory corruptions. A remote attacker could use this flaw to crash the system. (CVE-2017-2634, Moderate)

    Important: This update disables the DCCP kernel module at load time by using the kernel module blacklist     method. The module is disabled in an attempt to reduce further exposure to additional issues. Please see     Red Hat Bugzilla (BZ#1425177) for additional information.

    Red Hat would like to thank Andrey Konovalov (Google) for reporting CVE-2017-6074. The CVE-2017-2634 issue     was discovered by Wade Mealing (Red Hat Product Security).
