Test ID: | 1.3.6.1.4.1.25623.1.1.2.2020.1807 |
Category: | Huawei EulerOS Local Security Checks |
Title: | Huawei EulerOS: Security Advisory for kernel (EulerOS-SA-2020-1807) |
Summary: | The remote host is missing an update for the Huawei EulerOS 'kernel' package(s) announced via the EulerOS-SA-2020-1807 advisory. |
Description: | Summary: The remote host is missing an update for the Huawei EulerOS 'kernel' package(s) announced via the EulerOS-SA-2020-1807 advisory. Vulnerability Insight: An issue was discovered in the Linux kernel before 5.2. There is a NULL pointer dereference in tw5864_handle_frame() in drivers/media/pci/tw5864/tw5864-video.c, which may cause denial of service, aka CID-2e7682ebfc75.(CVE-2019-20806) A flaw was found in the ZRAM kernel module, where a user with a local account and the ability to read the /sys/class/zram-control/hot_add file can create ZRAM device nodes in the /dev/ directory. This read allocates kernel memory and is not accounted for a user that triggers the creation of that ZRAM device. With this vulnerability, continually reading the device may consume a large amount of system memory and cause the Out-of-Memory (OOM) killer to activate and terminate random userspace processes, possibly making the system inoperable.(CVE-2020-10781) In the Linux kernel before 5.4.16, a race condition in tty->disc_data handling in the slip and slcan line discipline could lead to a use-after-free, aka CID-0ace17d56824. This affects drivers/ net/slip/slip.c and drivers/ net/can/slcan.c.(CVE-2020-14416) The VFIO PCI driver in the Linux kernel through 5.6.13 mishandles attempts to access disabled memory space.(CVE-2020-12888) The flow_dissector feature in the Linux kernel 4.3 through 5.x before 5.3.10 has a device tracking vulnerability, aka CID-55667441c84f. This occurs because the auto flowlabel of a UDP IPv6 packet relies on a 32-bit hashrnd value as a secret, and because jhash (instead of siphash) is used. The hashrnd value remains the same starting from boot time, and can be inferred by an attacker. This affects net/core/flow_dissector.c and related code.(CVE-2019-18282) In the Linux kernel through 5.7.6, usbtest_disconnect in drivers/usb/misc/usbtest.c has a memory leak, aka CID-28ebeb8db770.(CVE-2020-15393) An issue was discovered in the Linux kernel before 5.0.6. In rx_queue_add_kobject() and netdev_queue_add_kobject() in net/core/ net-sysfs.c, a reference count is mishandled, aka CID-a3e23f719f5c.(CVE-2019-20811) A flaw was found in the Linux kernels SELinux LSM hook implementation before version 5.7, where it incorrectly assumed that an skb would only contain a single netlink message. The hook would incorrectly only validate the first netlink message in the skb and allow or deny the rest of the messages within the skb with the granted permission without further processing.(CVE-2020-10751) In the Android kernel in F2FS driver there is a possible out of bounds read due to a missing bounds check. This could lead to local information disclosure with system execution privileges needed. User interaction is not needed for exploitation.(CVE-2019-9445) A flaw was found in the Linux kernel's implementation of Userspace core dumps. This flaw allows an attacker with a local account to crash a trivial program and exfiltrate private kernel data.(CVE-2020-10732) go7007_snd_init in drivers/media/usb/go7007/snd-go7007.c in the Linux kernel ... [Please see the references for more information on the vulnerabilities] Affected Software/OS: 'kernel' package(s) on Huawei EulerOS V2.0SP8. 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 |
