CVE-2014-0077

Status Candidate

Overview

drivers/vhost/net.c in the Linux kernel before 3.13.10, when mergeable buffers are disabled, does not properly validate packet lengths, which allows guest OS users to cause a denial of service (memory corruption and host OS crash) or possibly gain privileges on the host OS via crafted packets, related to the handle_rx and get_rx_bufs functions.

Ubuntu Security Notice 2260-1 - A flaw was discovered in the Linux kernel's pseudo tty (pty) device. An unprivileged user could exploit this flaw to cause a denial of service (system crash) or potentially gain administrator privileges. Pinkie Pie discovered a flaw in the Linux kernel's futex subsystem. An unprivileged local user could exploit this flaw to cause a denial of service (system crash) or gain administrative privileges. Various other issues were also addressed.

Red Hat Security Advisory 2014-0629-01 - The rhev-hypervisor6 package provides a Red Hat Enterprise Virtualization Hypervisor ISO disk image. The Red Hat Enterprise Virtualization Hypervisor is a dedicated Kernel-based Virtual Machine hypervisor. It includes everything necessary to run and manage virtual machines: a subset of the Red Hat Enterprise Linux operating environment and the Red Hat Enterprise Virtualization Agent. OpenSSL is a toolkit that implements the Secure Sockets Layer and Transport Layer Security protocols, as well as a full-strength, general purpose cryptography library.

Red Hat Security Advisory 2014-0634-01 - The kernel packages contain the Linux kernel, the core of any Linux operating system. A flaw was found in the way the Linux kernel's netfilter connection tracking implementation for Datagram Congestion Control Protocol packets used the skb_header_pointer() function. A remote attacker could use this flaw to send a specially crafted DCCP packet to crash the system or, potentially, escalate their privileges on the system. A flaw was found in the way the Linux kernel's Adaptec RAID controller checked permissions of compat IOCTLs. A local attacker could use this flaw to bypass intended security restrictions.

A remote attacker could use this flaw to send a specially crafted DCCP packet to crash the system or, potentially, escalate their privileges on the system. A flaw was found in the way the handle_rx() function handled large network packets when mergeable buffers were disabled. A privileged guest user could use this flaw to crash the host or corrupt QEMU process memory on the host, which could potentially result in arbitrary code execution on the host with the privileges of the QEMU process.
