The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2019:2900 advisory.

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

    Security Fix(es):

    * A buffer overflow flaw was found in the way Linux kernel's vhost functionality that translates virtqueue     buffers to IOVs, logged the buffer descriptors during migration. A privileged guest user able to pass     descriptors with invalid length to the host when migration is underway, could use this flaw to increase     their privileges on the host. (CVE-2019-14835)

    * kernel: hw: Spectre SWAPGS gadget vulnerability (CVE-2019-1125)

    For more details about the security issue(s), including the impact, a CVSS score, acknowledgments, and     other related information, refer to the CVE page(s) listed in the References section.

    Bug Fix(es):

    * fs deadlock when a memory allocation waits on page writeback in NOFS context (BZ#1729105)

    * fragmented packets timing out (BZ#1729410)

    * kernel build: speed up debuginfo extraction (BZ#1731461)

    * use make -jN for modules_install (BZ#1735080)

    * shmem: consider shm_mnt as a long-term mount (BZ#1737375)

    * Backport TCP follow-up for small buffers (BZ#1739126)
