Ubuntu 16.10 : linux-raspi2 vulnerabilities (USN-3190-2)

critical Nessus Plugin ID 97098

Language:

New! Plugin Severity Now Using CVSS v3

The calculated severity for Plugins has been updated to use CVSS v3 by default. Plugins that do not have a CVSS v3 score will fall back to CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Synopsis

The remote Ubuntu host is missing one or more security-related patches.

Description

Mikulas Patocka discovered that the asynchronous multibuffer cryptographic daemon (mcryptd) in the Linux kernel did not properly handle being invoked with incompatible algorithms. A local attacker could use this to cause a denial of service (system crash).
(CVE-2016-10147)

It was discovered that a use-after-free existed in the KVM susbsystem of the Linux kernel when creating devices. A local attacker could use this to cause a denial of service (system crash). (CVE-2016-10150)

Qidan He discovered that the ICMP implementation in the Linux kernel did not properly check the size of an ICMP header. A local attacker with CAP_NET_ADMIN could use this to expose sensitive information.
(CVE-2016-8399)

Qian Zhang discovered a heap-based buffer overflow in the tipc_msg_build() function in the Linux kernel. A local attacker could use to cause a denial of service (system crash) or possible execute arbitrary code with administrative privileges. (CVE-2016-8632)

Dmitry Vyukov discovered that the KVM implementation in the Linux kernel did not properly restrict the VCPU index when I/O APIC is enabled, An attacker in a guest VM could use this to cause a denial of service (system crash) or possibly gain privileges in the host OS.
(CVE-2016-9777).

Note that Tenable Network Security has extracted the preceding description block directly from the Ubuntu security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Update the affected linux-image-4.8-raspi2 and / or linux-image-raspi2 packages.
