TITLE

Linux Kernel  Vulnerability in using cryptographic algorithms in

DESCRIPTION

In the IPv6 implementation in the Linux kernel before 5.13.3, net/ipv6/output_core.c has an information leak because of certain use of a hash table which, although big, doesn't properly consider that IPv6-based attackers can typically choose among many IPv6 source addresses. Linux Kernel Exists in the use of cryptographic algorithms.Information may be obtained. ========================================================================== Ubuntu Security Notice USN-5299-1 February 22, 2022 linux, linux-aws, linux-kvm, linux-lts-xenial vulnerabilities ========================================================================== A security issue affects these releases of Ubuntu and its derivatives: - Ubuntu 16.04 ESM - Ubuntu 14.04 ESM Summary: Several security issues were fixed in the Linux kernel. A physically proximate attacker could possibly use this issue to inject packets or exfiltrate selected fragments. (CVE-2020-26147) It was discovered that the bluetooth subsystem in the Linux kernel did not properly perform access control. An authenticated attacker could possibly use this to expose sensitive information. (CVE-2020-26558, CVE-2021-0129) It was discovered that the RPA PCI Hotplug driver implementation in the Linux kernel did not properly handle device name writes via sysfs, leading to a buffer overflow. A privileged attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code. (CVE-2021-33034) Norbert Slusarek discovered that the CAN broadcast manger (bcm) protocol implementation in the Linux kernel did not properly initialize memory in some situations. A local attacker could use this to expose sensitive information (kernel memory). (CVE-2021-34693) 马哲宇 discovered that the IEEE 1394 (Firewire) nosy packet sniffer driver in the Linux kernel did not properly perform reference counting in some situations, 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-2021-3483) It was discovered that the bluetooth subsystem in the Linux kernel did not properly handle HCI device initialization failure, leading to a double-free vulnerability. An attacker could use this to cause a denial of service or possibly execute arbitrary code. (CVE-2021-3564) Murray McAllister discovered that the joystick device interface in the Linux kernel did not properly validate data passed via an ioctl(). A local attacker could use this to cause a denial of service (system crash) or possibly execute arbitrary code on systems with a joystick device registered. (CVE-2021-3612) It was discovered that the tracing subsystem in the Linux kernel did not properly keep track of per-cpu ring buffer state. A privileged attacker could use this to cause a denial of service. (CVE-2021-3679) It was discovered that the MAX-3421 host USB device driver in the Linux kernel did not properly handle device removal events. A physically proximate attacker could use this to cause a denial of service (system crash). (CVE-2021-38204) It was discovered that the 6pack network protocol driver in the Linux kernel did not properly perform validation checks. A privileged attacker could use this to cause a denial of service (system crash) or execute arbitrary code. (CVE-2021-42008) Amit Klein discovered that the IPv6 implementation in the Linux kernel could disclose internal state in some situations. An attacker could possibly use this to expose sensitive information. (CVE-2021-45485) Update instructions: The problem can be corrected by updating your system to the following package versions: Ubuntu 16.04 ESM: linux-image-4.4.0-1100-kvm 4.4.0-1100.109 linux-image-4.4.0-1135-aws 4.4.0-1135.149 linux-image-4.4.0-219-generic 4.4.0-219.252 linux-image-4.4.0-219-lowlatency 4.4.0-219.252 linux-image-aws 4.4.0.1135.140 linux-image-generic 4.4.0.219.226 linux-image-kvm 4.4.0.1100.98 linux-image-lowlatency 4.4.0.219.226 linux-image-virtual 4.4.0.219.226 Ubuntu 14.04 ESM: linux-image-4.4.0-1099-aws 4.4.0-1099.104 linux-image-4.4.0-219-generic 4.4.0-219.252~14.04.1 linux-image-4.4.0-219-lowlatency 4.4.0-219.252~14.04.1 linux-image-aws 4.4.0.1099.97 linux-image-generic-lts-xenial 4.4.0.219.190 linux-image-lowlatency-lts-xenial 4.4.0.219.190 linux-image-virtual-lts-xenial 4.4.0.219.190 After a standard system update you need to reboot your computer to make all the necessary changes. ATTENTION: Due to an unavoidable ABI change the kernel updates have been given a new version number, which requires you to recompile and reinstall all third party kernel modules you might have installed. Unless you manually uninstalled the standard kernel metapackages (e.g. linux-generic, linux-generic-lts-RELEASE, linux-virtual, linux-powerpc), a standard system upgrade will automatically perform this as well.
