TOP VULNERABILITY THIS WEEK: Flaw within QEMU’s virtual Floppy Disk

Controller could allow VM escape (a.k.a. VENOM)


NOTABLE RECENT SECURITY ISSUES SELECTED BY THE TALOS SECURITY INTELLIGENCE AND RESEARCH GROUP

Title: Flaw within QEMU’s virtual Floppy Disk Controller could allow VM
escape (a.k.a. VENOM)
Description: CrowdStrike researchers have discovered a vulnerability
within QEMU that could allow attacker to escape the confines of a VM and
execute arbitrary code the host. In order to exploit this vulnerability
(which can be identified as CVE-2015-3456), an attack would need to have
administrative/root privileges on the affected host. Affected vendors
are aware of this vulnerability and have released advisories and
patches.

Title: Command Injection Vulnerability in Multiple Cisco TelePresence
Products Patched
Description: Cisco has issued an security advisory for several of its
TelePresence products. The vulnerability, identified by CVE-2015-0713,
is a flaw within the web framework of that “could allow an
authenticated, remote attacker to inject arbitrary commands that are
executed with the privileges of the root user.” Cisco has released a
software updates for affected products.

Title: Multiple Vendor Bash Remote Code Execution Vulnerability
Vendor: Multiple Vendors
Description: GNU Bash through 4.3 bash43-025 processes trailing strings
after certain malformed function definitions in the values of
environment variables, which allows remote attackers to write to files
or possibly have unknown other impact via a crafted environment, as
demonstrated by vectors involving the ForceCommand feature in OpenSSH
sshd, the mod_cgi and mod_cgid modules in the Apache HTTP Server,
scripts executed by unspecified DHCP clients, and other situations in
which setting the environment occurs across a privilege boundary from
Bash execution. NOTE: this vulnerability exists because of an incomplete
fix for CVE-2014-6271.
CVSS v2 Base Score: 10.0 (AV:N/AC:L/Au:N/C:C/I:C/A:C)

ID: CVE-2014-6271
Title: Multiple Vendor Bash Remote Code Execution Vulnerability
Vendor: Multiple Vendors
Description: GNU Bash through 4.3 processes trailing strings after
function definitions in the values of environment variables, which
allows remote attackers to execute arbitrary code via a crafted
environment, as demonstrated by vectors involving the ForceCommand
feature in OpenSSH sshd, the mod_cgi and mod_cgid modules in the Apache
HTTP Server, scripts executed by unspecified DHCP clients, and other
situations in which setting the environment occurs across a privilege
boundary from Bash execution, aka “ShellShock.” NOTE: the original fix
