| Description: | Summary:
The remote host is missing an update for the 'linux, linux-aws, linux-azure, linux-gcp, linux-kvm, linux-oracle, linux-raspi, linux-riscv' package(s) announced via the USN-4411-1 advisory.
Vulnerability Insight:
It was discovered that the elf handling code in the Linux kernel did not
initialize memory before using it in certain situations. A local attacker
could use this to possibly expose sensitive information (kernel memory).
(CVE-2020-10732)
Matthew Sheets discovered that the SELinux network label handling
implementation in the Linux kernel could be coerced into de-referencing a
NULL pointer. A remote attacker could use this to cause a denial of service
(system crash). (CVE-2020-10711)
It was discovered that the SCSI generic (sg) driver in the Linux kernel did
not properly handle certain error conditions correctly. A local privileged
attacker could use this to cause a denial of service (system crash).
(CVE-2020-12770)
It was discovered that the USB Gadget device driver in the Linux kernel did
not validate arguments passed from configfs in some situations. A local
attacker could possibly use this to cause a denial of service (system
crash) or possibly expose sensitive information. (CVE-2020-13143)
It was discovered that the KVM implementation in the Linux kernel did not
properly deallocate memory on initialization for some processors. A local
attacker could possibly use this to cause a denial of service.
(CVE-2020-12768)
Affected Software/OS:
'linux, linux-aws, linux-azure, linux-gcp, linux-kvm, linux-oracle, linux-raspi, linux-riscv' package(s) on Ubuntu 20.04.
Solution:
Please install the updated package(s).
