Title:	SUSE: Security Advisory (SUSE-SU-2020:3503-1)
Summary:	The remote host is missing an update for the 'Linux Kernel' package(s) announced via the SUSE-SU-2020:3503-1 advisory.
Description:	Summary: The remote host is missing an update for the 'Linux Kernel' package(s) announced via the SUSE-SU-2020:3503-1 advisory. Vulnerability Insight: The SUSE Linux Enterprise 12 SP3 kernel was updated to receive various security and bug fixes. The following security bugs were fixed: CVE-2020-25705: A flaw in the way reply ICMP packets are limited in was found that allowed to quickly scan open UDP ports. This flaw allowed an off-path remote user to effectively bypassing source port UDP randomization. The highest threat from this vulnerability is to confidentiality and possibly integrity, because software and services that rely on UDP source port randomization (like DNS) are indirectly affected as well. Kernel versions may be vulnerable to this issue (bsc#1175721, bsc#1178782). CVE-2020-25668: Fixed a use-after-free in con_font_op() (bsc#1178123). CVE-2020-25656: Fixed a concurrency use-after-free in vt_do_kdgkb_ioctl (bnc#1177766). CVE-2020-14351: Fixed a race in the perf_mmap_close() function (bsc#1177086). CVE-2020-8694: Restricted 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 a use-after-free in the fast user mutex (futex) wait operation, which could have lead to memory corruption and possibly privilege escalation (bsc#1176011). CVE-2020-25212: Fixed A TOCTOU mismatch in the NFS client code which could have been used by local attackers to corrupt memory (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-2020-25641: Fixed a zero-length biovec request issued by the block subsystem could have caused the kernel to enter an infinite loop, causing a denial of service (bsc#1177121). 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). CVE-2019-19063: ...
