The SUSE Linux Enterprise 12 SP3 Teradata kernel was updated to receive various security and bug fixes.
The following security bugs were fixed:
- CVE-2020-25656: Fixed a concurrency use-after-free in vt_do_kdgkb_ioctl (bnc#1177766). - CVE-2017-18204: Fixed a denial of service in the ocfs2_setattr function of fs/ocfs2/file.c (bnc#1083244). - CVE-2020-14351: Fixed a race in the perf_mmap_close() function (bsc#1177086). - CVE-2020-8694: Restrict energy meter to root access (bsc#1170415). - CVE-2020-12352: Fixed an information leak when processing certain AMP packets aka 'BleedingTooth' (bsc#1177725). - CVE-2020-25645: Fixed an issue which traffic between two Geneve endpoints may be unencrypted when IPsec is configured to encrypt traffic for the specific UDP port used by the GENEVE tunnel allowing anyone between the two endpoints to read the traffic unencrypted (bsc#1177511). - CVE-2020-14381: Fixed requeue paths such that filp was valid when dropping the references (bsc#1176011). - CVE-2020-25212: Fixed a TOCTOU mismatch in the NFS client code (bsc#1176381). - CVE-2020-14390: Fixed an out-of-bounds memory write leading to memory corruption or a denial of service when changing screen size (bnc#1176235). - CVE-2020-25643: Fixed a memory corruption and a read overflow which could have caused by improper input validation in the ppp_cp_parse_cr function (bsc#1177206). - CVE-2020-26088: Fixed an improper CAP_NET_RAW check in NFC socket creation could have been used by local attackers to create raw sockets, bypassing security mechanisms (bsc#1176990). - CVE-2020-0432: Fixed an out of bounds write due to an integer overflow (bsc#1176721). - CVE-2020-0431: Fixed an out of bounds write due to a missing bounds check (bsc#1176722). - CVE-2020-0427: Fixed an out of bounds read due to a use after free (bsc#1176725). - CVE-2020-0404: Fixed a linked list corruption due to an unusual root cause (bsc#1176423). - CVE-2020-25284: Fixed an incomplete permission checking for access to rbd devices, which could have been leveraged by local attackers to map or unmap rbd block devices (bsc#1176482).
The following non-security bugs were fixed:
- getxattr: use correct xattr length (bnc#1012382, bnc#1161556). - hv: vmbus: Fix ring buffer signaling (bsc#1118506, bsc#1178327). - XEN uses irqdesc::irq_data_common::handler_data to store a per interrupt XEN data pointer which contains XEN specific information (XSA-332 bsc#1065600). - xen/blkback: use lateeoi irq binding (XSA-332 bsc#1177411). - xen/events: add a new 'late EOI' evtchn framework (XSA-332 bsc#1177411). - xen/events: add a proper barrier to 2-level uevent unmasking (XSA-332 bsc#1177411). - xen/events: avoid removing an event channel while handling it (XSA-331 bsc#1177410). - xen/events: block rogue events for some time (XSA-332 bsc#1177411). - xen/events: defer eoi in case of excessive number of events (XSA-332 bsc#1177411). - xen/events: do not use chip_data for legacy IRQs (XSA-332 bsc#1065600). - xen/events: fix race in evtchn_fifo_unmask() (XSA-332 bsc#1177411). - xen/events: switch user event channels to lateeoi model (XSA-332 bsc#1177411). - xen/events: use a common cpu hotplug hook for event channels (XSA-332 bsc#1177411). - xen/netback: use lateeoi irq binding (XSA-332 bsc#1177411). - xen/pciback: use lateeoi irq binding (XSA-332 bsc#1177411). - xen/scsiback: use lateeoi irq binding (XSA-332 bsc#1177411).
