Synopsis

The remote SUSE host is missing one or more security updates.

Description

The SUSE Linux Enterprise 12 SP3 kernel was updated to receive various security and bugfixes.

The following security bugs were fixed :

CVE-2020-11494: An issue was discovered in slc_bump in drivers/net/can/slcan.c, which allowed attackers to read uninitialized can_frame data, potentially containing sensitive information from kernel stack memory, if the configuration lacks CONFIG_INIT_STACK_ALL (bnc#1168424).

CVE-2020-10942: In get_raw_socket in drivers/vhost/net.c lacks validation of an sk_family field, which might allow attackers to trigger kernel stack corruption via crafted system calls (bnc#1167629).

CVE-2020-8647: Fixed a use-after-free vulnerability in the vc_do_resize function in drivers/tty/vt/vt.c (bnc#1162929).

CVE-2020-8649: Fixed a use-after-free vulnerability in the vgacon_invert_region function in drivers/video/console/vgacon.c (bnc#1162931).

CVE-2020-9383: Fixed an issue in set_fdc in drivers/block/floppy.c, which leads to a wait_til_ready out-of-bounds read (bnc#1165111).

CVE-2019-9458: In the video driver there was a use after free due to a race condition. This could lead to local escalation of privilege with no additional execution privileges needed (bnc#1168295).

CVE-2019-3701: Fixed an issue in can_can_gw_rcv, which could cause a system crash (bnc#1120386).

CVE-2019-19768: Fixed a use-after-free in the __blk_add_trace function in kernel/trace/blktrace.c (bnc#1159285).

CVE-2020-11609: Fixed a NULL pointer dereference in the stv06xx subsystem caused by mishandling invalid descriptors (bnc#1168854).

CVE-2020-10720: Fixed a use-after-free read in napi_gro_frags() (bsc#1170778).

CVE-2020-10690: Fixed the race between the release of ptp_clock and cdev (bsc#1170056).

CVE-2019-9455: Fixed a pointer leak due to a WARN_ON statement in a video driver. This could lead to local information disclosure with System execution privileges needed (bnc#1170345).

CVE-2020-11608: Fixed an issue in drivers/media/usb/gspca/ov519.c caused by a NULL pointer dereferences in ov511_mode_init_regs and ov518_mode_init_regs when there are zero endpoints (bnc#1168829).

CVE-2017-18255: The perf_cpu_time_max_percent_handler function in kernel/events/core.c allowed local users to cause a denial of service (integer overflow) or possibly have unspecified other impact via a large value, as demonstrated by an incorrect sample-rate calculation (bnc#1087813).

CVE-2020-8648: There was a use-after-free vulnerability in the n_tty_receive_buf_common function in drivers/tty/n_tty.c (bnc#1162928).

CVE-2020-2732: A flaw was discovered in the way that the KVM hypervisor handled instruction emulation for an L2 guest when nested virtualisation is enabled. Under some circumstances, an L2 guest may trick the L0 guest into accessing sensitive L1 resources that should be inaccessible to the L2 guest (bnc#1163971).

CVE-2019-5108: Fixed a denial-of-service vulnerability caused by triggering AP to send IAPP location updates for stations before the required authentication process has completed (bnc#1159912).

CVE-2020-8992: ext4_protect_reserved_inode in fs/ext4/block_validity.c allowed attackers to cause a denial of service (soft lockup) via a crafted journal size (bnc#1164069).

CVE-2018-21008: Fixed a use-after-free which could be caused by the function rsi_mac80211_detach in the file drivers/net/wireless/rsi/rsi_91x_mac80211.c (bnc#1149591).

CVE-2019-14896: A heap-based buffer overflow vulnerability was found in 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 (bnc#1157157).

CVE-2019-14897: A stack-based buffer overflow was found in Marvell WiFi chip driver. An attacker is 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 (bnc#1157155).

CVE-2019-18675: Fixed an integer overflow in cpia2_remap_buffer in drivers/media/usb/cpia2/cpia2_core.c because cpia2 has its own mmap implementation. This allowed local users (with /dev/video0 access) to obtain read and write permissions on kernel physical pages, which can possibly result in a privilege escalation (bnc#1157804).

CVE-2019-14615: Insufficient control flow in certain data structures for some Intel(R) Processors with Intel(R) Processor Graphics may have allowed an unauthenticated user to potentially enable information disclosure via local access (bnc#1160195, bsc#1165881).

CVE-2019-19965: Fixed a NULL pointer dereference in drivers/scsi/libsas/sas_discover.c because of mishandling of port disconnection during discovery, related to a PHY down race condition (bnc#1159911).

CVE-2019-20054: Fixed a NULL pointer dereference in drop_sysctl_table() in fs/proc/proc_sysctl.c, related to put_links (bnc#1159910).

CVE-2019-20096: Fixed a memory leak in __feat_register_sp() in net/dccp/feat.c, which may cause denial of service (bnc#1159908).

CVE-2019-19966: Fixed a use-after-free in cpia2_exit() in drivers/media/usb/cpia2/cpia2_v4l.c that will cause denial of service (bnc#1159841).

CVE-2019-19447: Fixed an issue with mounting a crafted ext4 filesystem image, performing some operations, and unmounting could lead to a use-after-free in ext4_put_super in fs/ext4/super.c, related to dump_orphan_list in fs/ext4/super.c (bnc#1158819).

CVE-2019-19319: Fixed an issue with a setxattr operation, after a mount of a crafted ext4 image, can cause a slab-out-of-bounds write access because of an ext4_xattr_set_entry use-after-free in fs/ext4/xattr.c when a large old_size value is used in a memset call (bnc#1158021).

CVE-2019-19767: Fixed mishandling of ext4_expand_extra_isize, as demonstrated by use-after-free errors in __ext4_expand_extra_isize and ext4_xattr_set_entry, related to fs/ext4/inode.c and fs/ext4/super.c (bnc#1159297).

CVE-2019-11091,CVE-2018-12126,CVE-2018-12130,CVE-2018-12127: Earlier mitigations for the 'MDS' Microarchitectural Data Sampling attacks were not complete. An additional fix was added to the x86_64 fast systemcall path to further mitigate these attacks. (bsc#1164846 bsc#1170847)

The update package also includes non-security fixes. See advisory for details.
