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

A flaw was discovered in the Linux kernel's macvtap device driver, which is used in KVM (Kernel-based Virtual Machine) to create a network bridge between host and guest. A privleged user in a guest could exploit this flaw to crash the host, if the vhost_net module is loaded with the experimental_zcopytx option enabled. (CVE-2012-2119)

An error was discovered in the Linux kernel's network TUN/TAP device implementation. A local user with access to the TUN/TAP interface (which is not available to unprivileged users until granted by a root user) could exploit this flaw to crash the system or potential gain administrative privileges. (CVE-2012-2136)

A flaw was found in how the Linux kernel's KVM (Kernel-based Virtual Machine) subsystem handled MSI (Message Signaled Interrupts). A local unprivileged user could exploit this flaw to cause a denial of service or potentially elevate privileges. (CVE-2012-2137)

A flaw was found in the Linux kernel's Reliable Datagram Sockets (RDS) protocol implementation. A local, unprivileged user could use this flaw to cause a denial of service. (CVE-2012-2372)

Ulrich Obergfell discovered an error in the Linux kernel's memory management subsystem on 32 bit PAE systems with more than 4GB of memory installed. A local unprivileged user could exploit this flaw to crash the system. (CVE-2012-2373)

Dan Rosenberg discovered flaws in the Linux kernel's NCI (Near Field Communication Controller Interface). A remote attacker could exploit these flaws to crash the system or potentially execute privileged code. (CVE-2012-3364)

A flaw was discovered in the Linux kernel's epoll system call. An unprivileged local user could use this flaw to crash the system.
(CVE-2012-3375)

Some errors where discovered in the Linux kernel's UDF file system, which is used to mount some CD-ROMs and DVDs. An unprivileged local user could use these flaws to crash the system. (CVE-2012-3400)

Solution

Update the affected package(s).
