Title:	SUSE: Security Advisory (SUSE-SU-2020:14442-1)
Summary:	The remote host is missing an update for the 'Linux Kernel' package(s) announced via the SUSE-SU-2020:14442-1 advisory.
Description:	Summary: The remote host is missing an update for the 'Linux Kernel' package(s) announced via the SUSE-SU-2020:14442-1 advisory. Vulnerability Insight: The SUSE Linux Enterprise 11 SP4 kernel was updated to receive various security and bugfixes. The following security bugs were fixed: CVE-2020-10773: Fixed a memory leak on s390/s390x, in the cmm_timeout_hander in file arch/s390/mm/cmm.c (bnc#1172999). CVE-2020-14416: Fixed a race condition in tty->disc_data handling in the slip and slcan line discipline could lead to a use-after-free. This affects drivers/net/slip/slip.c and drivers/net/can/slcan.c (bnc#1162002). CVE-2020-13974: Fixed a integer overflow in drivers/tty/vt/keyboard.c, if k_ascii is called several times in a row (bnc#1172775). CVE-2020-10732: A flaw was found in the implementation of Userspace core dumps. This flaw allowed an attacker with a local account to crash a trivial program and exfiltrate private kernel data (bnc#1171220). CVE-2020-12656: Fixed a memory leak in gss_mech_free in the rpcsec_gss_krb5 implementation, caused by a lack of certain domain_release calls (bnc#1171219). CVE-2020-0305: Fixed a possible use-after-free due to a race condition incdev_get of char_dev.c. This could lead to local escalation of privilege. User interaction is not needed for exploitation (bnc#1174462). CVE-2020-10769: A buffer over-read flaw was found in crypto_authenc_extractkeys in crypto/authenc.c in the IPsec Cryptographic algorithm's module, authenc. This flaw allowed a local attacker with user privileges to cause a denial of service (bnc#1173265). CVE-2020-12652: The __mptctl_ioctl function in drivers/message/fusion/mptctl.c allowed local users to hold an incorrect lock during the ioctl operation and trigger a race condition, i.e., a 'double fetch' vulnerability (bnc#1171218). CVE-2019-5108: Fixed a denial-of-service vulnerability in the wifi stack. An attacker could exploit this vulnerability by triggering AP to send IAPP location updates for stations before the required authentication process has completed (bnc#1159912). The following non-security bugs were fixed: Fix gcc-discovered error in zeroing a struct (bnc#680814) Affected Software/OS: 'Linux Kernel' package(s) on SUSE Linux Enterprise Debuginfo 11-SP4, SUSE Linux Enterprise Server 11, SUSE Linux Enterprise Server 11-SP4. Solution: Please install the updated package(s). CVSS Score: 7.2 CVSS Vector: AV:L/AC:L/Au:N/C:C/I:C/A:C
