   An update that solves 5 vulnerabilities and has three fixes
   is now available.

Description:

   This update for the Linux Kernel 4.12.14-120 fixes several issues.

   The following security issues were fixed:

   - CVE-2019-14896: A heap-based buffer overflow vulnerability was found in
     the Marvell WiFi chip driver. A remote attacker could cause a denial of
     service (system crash) or, possibly execute arbitrary code, when the
     lbs_ibss_join_existing function is called after a STA connects to an AP
     (bsc#1157157).
   - CVE-2019-14897: A stack-based buffer overflow was found in the  Marvell
     WiFi chip driver. An attacker was able to cause a denial of service
     (system crash) or, possibly execute arbitrary code, when a STA works in
     IBSS mode (allows connecting stations together without the use of an AP)
     and connects to another STA (bsc#1157155).
   - CVE-2019-10220: The CIFS implementation was vulnerable to a relative
     paths injection in directory entry lists (bsc#1144903).
   - CVE-2019-17133: Fixed a Buffer Overflow in cfg80211_mgd_wext_giwessid()
     in net/wireless/wext-sme.c, because the function did not reject a long
     SSID IE (bsc#1153158).
   - CVE-2019-14835: A buffer overflow flaw was fixed in the 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
     (bsc#1150112).
   - xen/pv: Fixed a boot up hang where domain_crash_sync was called from
     entry.S (bsc#1153811).
