Overview

Information on CVE-2015-5154 was made public on July 27, 2015. The vulnerability is in QEMU, a generic and open source machine emulator and virtualizer that is utilized by Xen, KVM, and other modern hypervisors / virtualization platforms.

VENOM, or Virtualized Environment Neglected Operations Manipulation, was made public on May 13, 2015. The vulnerability is in QEMU, a generic and open source machine emulator and virtualizer that is utilized by Xen, KVM, and other modern hypervisors / virtualization platforms.

A vulnerability found in the glibc library, specifically a flaw affecting the gethostbyname() and gethostbyname2() function calls, that allows a remote attacker to potentially execute arbitrary code. CentOS 5, CentOS 6, and CentOS 7 are potentially affected, thus we want to highlight the following information.

A vulnerability found in the Linux kernel, specifically a flaw in fault handling associated with the Stack Segment (SS), allows an unprivileged user to potentially gain privileges. CentOS 4, CentOS 5, CentOS 6, and CentOS 7 are potentially affected, thus we want to highlight the following information.

On September 24th, a vulnerability was reported in the GNU Bourne-Again-Shell (BASh, or Bash), specifically a flaw with how Bash processes values of environment variables, that allows remote code execution of varying types in many common configurations. The overall risk is severe due to bash being configured for use, by default, on most Linux servers.

OpenSSL is a common cryptographic library which provides encryption, specifically SSL/TLS, for popular applications such as Apache (web), MySQL (database), e-mail, virtual private networks (VPNs), and more.

What is OpenSSL?

A vulnerability found in the Linux kernel, specifically a flaw with the pseudo tty (pty) device, allows an unprivileged user to cause a denial of service (system crash) or potentially gain administrator privileges. A small number of CentOS and Ubuntu versions are vulnerable, thus we want to highlight the following information:
