______________________________________________________________________________
An update that solves 7 vulnerabilities and has four fixes is now available.
Description:
The SUSE Linux Enterprise 11 SP4 kernel was updated to receive various security
and bugfixes.
The following security bugs were fixed:
o CVE-2019-3459: A heap address information leak while using
L2CAP_GET_CONF_OPT was discovered in the Linux kernel(bnc#1120758).
o CVE-2019-3460: A heap data infoleak in multiple locations including
L2CAP_PARSE_CONF_RSP was found in the Linux kernel before (bnc#1120758).
o CVE-2019-3896: A double-free could happen in idr_remove_all() in lib/idr.c
in the Linux kernel. An unprivileged local attacker could use this flaw for
a privilege escalation or for a system crash and a denial of service (DoS)
(bnc#1138943).
o CVE-2018-5390: The Linux kernel could be forced to make very expensive
calls to tcp_collapse_ofo_queue() and tcp_prune_ofo_queue() for every
incoming packet which could lead to a denial of service (bnc#1102340).
o CVE-2018-20836: An issue was discovered in the Linux kernel There was a
race condition in smp_task_timedout() and smp_task_done() in drivers/scsi/
libsas/sas_expander.c, leading to a use-after-free (bnc#1134395).
o CVE-2019-12614: An issue was discovered in dlpar_parse_cc_property in arch/
powerpc/platforms/pseries/dlpar.c in the Linux kernel There was an
unchecked kstrdup of prop-name, which might allow an attacker to cause a
denial of service (NULL pointer dereference and system crash) (bnc#
1137194).
o CVE-2019-3846: A flaw that allowed an attacker to corrupt memory and
possibly escalate privileges was found in the mwifiex kernel module while
connecting to a malicious wireless network (bnc#1136424 1136446).
The following non-security bugs were fixed:
o KEYS: do not let add_key() update an uninstantiated key (bnc#1063416).
o fnic: Fix to cleanup aborted IO to avoid device being offlined by mid-layer
(bsc#1134835).
o signal: give SEND_SIG_FORCED more power to beat SIGNAL_UNKILLABLE (bsc#
1135650).
o signal: oom_kill_task: use SEND_SIG_FORCED instead of force_sig() (bsc#
1135650).
o tcp: a regression in the previous fix for the TCP SACK issue was fixed (bnc
#1139751)
