______________________________________________________________________________

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).
