Ubuntu 16.04 ESM : Linux kernel vulnerabilities (USN-5361-1)

high Nessus Plugin ID 159387

Language:

Synopsis

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

Description

The remote Ubuntu 16.04 ESM host has a package installed that is affected by multiple vulnerabilities as referenced in the USN-5361-1 advisory.

 It was discovered that the VFIO PCI driver in the Linux kernel did not properly handle attempts to access disabled memory spaces. A local attacker could use this to cause a denial of service (system crash).
 (CVE-2020-12888)

 Mathy Vanhoef discovered that the Linux kernels WiFi implementation did not properly verify certain fragmented frames. A physically proximate attacker could possibly use this issue to inject or decrypt packets. (CVE-2020-26141)

 Mathy Vanhoef discovered that the Linux kernels WiFi implementation accepted plaintext fragments in certain situations. A physically proximate attacker could use this issue to inject packets.
 (CVE-2020-26145)

 It was discovered that a race condition existed in the Atheros Ath9k WiFi driver in the Linux kernel. An attacker could possibly use this to expose sensitive information (WiFi network traffic). (CVE-2020-3702)

 It was discovered a race condition existed in the Unix domain socket implementation in the Linux kernel, leading to a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-0920)

 It was discovered that the IPv6 implementation in the Linux kernel contained a use-after-free vulnerability. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-0935)

 Zygo Blaxell discovered that the btrfs file system implementation in the Linux kernel contained a race condition during certain cloning operations. A local attacker could possibly use this to cause a denial of service (system crash). (CVE-2021-28964)

 Dan Carpenter discovered that the block device manager (dm) implementation in the Linux kernel contained a buffer overflow in the ioctl for listing devices. A privileged local attacker could use this to cause a denial of service (system crash). (CVE-2021-31916)

 It was discovered that the Option USB High Speed Mobile device driver in the Linux kernel did not properly handle error conditions. A physically proximate attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-37159)

 It was discovered that the network packet filtering implementation in the Linux kernel did not properly initialize information in certain circumstances. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2021-39636)

 Jann Horn discovered a race condition in the Unix domain socket implementation in the Linux kernel that could result in a read-after-free. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-4083)

 Luo Likang discovered that the FireDTV Firewire driver in the Linux kernel did not properly perform bounds checking in some situations. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-42739)

 Brendan Dolan-Gavitt discovered that the Marvell WiFi-Ex USB device driver in the Linux kernel did not properly handle some error conditions. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2021-43976)

 Amit Klein discovered that the IPv4 implementation in the Linux kernel could disclose internal state in some situations. An attacker could possibly use this to expose sensitive information. (CVE-2021-45486)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Update the affected kernel package.
